Bug Description

The issue i'm having is with the initial installation.

I run Windows XP Home Edition on an HP Pavilion a656x with an added video card and an added stick of memory. It has two optical drives, drive E (a DVD/CD drive) and drive F (a CD drive).

Here is what happens...

1. I boot into Windows XP
2. I insert the Ubuntu 9.04 CD into drive E
3. I get a pop-up message window (from pyrun.exe) telling me that there is no disk in drive F
4. My options are Cancel, Try Again, and Continue and the "X" to close the little window
5. no matter what i click, the error message just pops back up.

if I put the CD in the Drive F, then everything happens exactly the same except that in step 3, the message informs me there is no disk in drive E.

So, whichever of my two drives i insert the CD into, the installer complains that i don't have a disk in the OTHER drive.

In Ubuntu 8.10 (which I no longer have installed on my system), after I inserted the CD, I would simply get a pop-up that presented 3 installation options (and I want to choose the 2nd one: install inside windows)....in Ubuntu 9.04, if i keep clicking the various buttons randomly like 50 times (Cancel, Try Again, Continue, and the little close "X")...I will eventually get the installation options.

---------------------------------

UPDATE:
I am the author of this bug report, which I reported in april 2009. It is now January 2010, and I have decided to sum up the issue and the work around so people won't read the first 5 or 6 posts and misunderstand the issue. I am still getting email notifications; so, apparently this is still a problem.

APPARENT CAUSE:
This issue appears to be due to the wubi installer being ported to python from its original language; therefore, if i remember correctly, this problem will only be seen on wubi 9.04 and later. Wubi (and possibly python itself) has problems dealing elegantly with empty data storage devices in certain instances. Wubi scans all drives on your system a certain number of times during the installation process. Every time it scans through the drives and encounters one it does not know how to deal with, it produces this error. If you click through it, wubi moves on to the next drive.

WHAT TO EXPECT:
It feels like an infinite loop or like windows must be rebooted, but, it is nothing so serious. Wubi scans the through all drives several times during the installation process and produces this error message any time it encounters a drive it doesn't understand. If you click the error message, wubi simply scans the next drive. If you keep clicking through the error message, wubi will eventually have scanned all the drives and move on.

For example, my computer had a card reader with 4 slots. Each slot was considered a drive and each slot produced an error. Wubi scanned my drives 3 times during the installation, so I had to click through the error message a total of 12 times.

POSSIBLE PROBLEM DEVICES:
- card readers (usually each slot will produce the error)
- empty CD or DVD drives (not all people experience issues with these...my CD and DVD drive did not produce any errors)
- virtual drives
- drives assigned non-ascii drive letter

MORE ABOUT DEVICES:
- built-in card readers appear to be the most commonly reported problem device
- on the ubuntu forums, I have read that someone had this issue due to an attached cell phone
- some printers, keyboards, or monitors can have a built-in card reader...don't forget to check that

WORKAROUND (TEMPORARY SOLUTION):
1. Eject the problem devices, OR...
2. Click through the error messages -- it is not an infinite loop, you will get one error message per problem device each time wubi scans the drives.

forgive the mistake again...i am still not writing that last paragraph clearly. The entire last paragraph of my original bug report should read as below:

With the Ubuntu 8.10 CD, after I insert the CD, I correctly get a pop-up that presents 3 installation options (and I want to choose the 2nd one: install inside windows). With the 9.04 CD, however, i get this error message box and, sometimes, if i keep clicking the various buttons on the error message window randomly like 50 times (Cancel, Try Again, Continue, and the little close "X")...I MIGHT eventually get the installation options. But sometimes I cannot get to the installation options at all (in which case, i must actually restart windows to get rid of the pop-up error message).

update...

1. i restarted windows and then inserted the 9.04 CD.
2. the message is now "Exception Processing Message c0000013 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c"
3. clicking "cancel" or the "X" on the error message 8 times gets me to the installation options dialog.

i restarted windows again with same results. i decided to go ahead with the installation at this point, so i clicked "install inside windows"

the installation went okay except at certain points the error message "Exception Processing Message c0000013 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c" would pop up and i would have to click cancel 4 times (not 8 as at the beginning) in order to get the installation to continue.

once installed, ubuntu 9.04 is working okay for me so far (i am writing this comment from it).

Pyrun.exe takes such a death grip that it can't be canceled with Task Manager.

This probably happens while Wubi scans all your drives for a CD/ISO, it would help if you could identify the drive that originates this message by looking at the wubi log in your user temp folder as soon as you see the error dialog.

Apologies for "hijacking" this bug report

D'oh! A little while back I rechecked the attached logs: seems I was using rev 122 of Wubi 9.04 with the "release candidate" disk for 9.04......
No signs of the mentioned worm, removing quicktime (as suggested in one of the discussions returned by Google (wonderful friend!) didn't help, no sign of "dit.exe" mentioned by another thread......
Clearing the list of recent documents (suggested somewhere else) didn't help....
No sign of error dialog when using an 8.10 32-bit disk from Cannonical....
Downloading rev 129 & a fresh ISO for the 64-bit version (placed in same folder) didn't seem to help.

Surprise surprise, no sign of the previous error messages.

I don't have time to pinpoint the exact reason for the problems on my machine at the moment (whether it's malware or conflict with something else installed on my system) but will post any additional clues as they come to mind. If doing a fresh install of XP (or whatever) is too drastic, then the links already provided by Agostino Russo might be able to provide a few ideas to check.

Good luck everyone!

Trying to run Wubi on an XP virtual machine and on a Win 7 Beta virtualbox machine, it seems to run fine, no error messages noticed (I didn't complete the installation because of lack of disk space in my virtual machine) and AVG free 8.0 is installed in both of them. So the problem, in my case, is not directly connected with AVG, or at least it seems not to be.

Agostino Russo (ago) wrote :

The above logs are fine, there is no error which is visible by the application. The issue probably manifest itself when trying to access a particular drive of yours. A lot of programs mentioned by other users are not really the cause, they simply scan the available drives similarly to what Wubi does, and trigger the error. You might first want to identify the drive, possibly by reducing the number of drives until you find the one responsible.

i have 2 optical drives. Drive E (a dvd burner) and drive F (a cd-rom). As long as BOTH drives contain an ubuntu ISO image (for example, if drive E already has the ubuntu 8.10 disk in it), then when i insert the 9.04 disk, i do NOT get the error. On the other hand, if i have no disk or a non-ubuntu disk in drive in drive E, then when i insert the 9.04 disk in drive F, i get the error.

it seems that wubi 9.04 has changed, in some fundamental way, the method by which it interacts with the drives and it causes windows xp to generate the "no disk" error when wubi interacts with an optical drive that doesn't contain a valid ubuntu ISO image (at least on my computer).

Again, wubi 8.10 does NOT produce these errors.

I think that it's probably NOT the AV blocking something, and possibly not SP3 either. I also noticed that the 8.10 disk didn't have the error while the 9.04 did. I, too, suspect that something has changed with the way 9.04 interacts with the disk, but haven't had a chance to do informal tests yet.

I can confirm that the card-reader might have some connection (direct or otherwise) with the difficulties: on my XP machine, I clicked on "safely remove hardware" for the built-in card reader, and the error message failed to appear. A restart (to reconnect the card reader) and the error returned. Looking to lspci for clues to manufactures, it wasn't immediately obvious which (internal) USB port was responsible for the card reader, but ATI was mentioned a few times.

Trying the same disk on another machine with a built-in card reader, but running Vista. there was no error. This machine has what lspci describes as a Texas Instruments 5-in-1 multimedia card reader (SD/MMC/MS/MS PRO/xD)

I also think that the problem is connected with the card reader. I have an
economic USB built-in card reader (a generic one) and, running wubi after
clicking on safely remove hardware to disconnect card reader, it starts
without any error. Rebooting the computer (to reconnect the device): the "no
disk" error appears when I start wubi.

i have the same results. if i "remove" my card reader (i.e., click on "safely remove hardware"), then my various usb / memory card drives are no longer viewable AND wubi 9.04 works fine.

all of my volume labels are ascii characters (i don't remember the exact letters and i will have to restart windows to view them again, but they were simple capital letters like G:, H:, I:, J:, K:)

from what i can see, wubi has been (is being) ported to python from some other language (largely due to the efforts of Agostino Russo, if i understand correctly). that's a tremendous project and appears to be done by a small number of people. so, we can definitely expect some hiccups.

I've also been experiencing the same issue when trying to install Ubuntu or Kubuntu 9.04. Doesn't matter if I download the distribution or download Wubi, I get this error message from pyrun.exe:

There is no disk in the drive. Please insert a disk into drive \Device\Harddisk2\DR2

and I can either cancel, try again, or continue.

I'm running Windows 7 RC at the moment.

If I click on Try Again twice or Continue, it'll still launch the setup menu for the distribution, but I never had this problem until after I installed Ubuntu (which I then removed due to video card problems when trying to launch Ubuntu) and downloaded Python 3.0 from the repository.

Using Win XP Professional:
I had the problem first without an error message (on a laptop) - Wubi made the drive lamp blink for a minute or so and then went back to sleep. On the other machine wubi exe on the 9.04 disc and the downloaded installer both produced the insistent error message from pyrun, which itself was hard to get rid of.
I tried closing down all peripherals but to no avail: finally I tried the "desperate click" method described above and eventually I got the installer window. My Kaspersky asked several times if I would allow pyrun to communicate with home (wherever that may be) and I did; after that installation proceeded normally.
 Obviously a bug, and one that is not going to encourage new users to use either Wubi or Ubuntu. Let's hope someone can fix it!

Chuck Thayer (catintp) wrote :

I had the same issue with Win XP SP 3.

To get by the impasse, I just put a data CD with a valid directory structure into the drive. Wubi was able to read it, and to determine that it contains nothing of interest to Ubuntu. Once Wubi verified that (a) there was a disk in the drive, and (b) it was not the disk it wanted, it started to automatically download the files it needed to go ahead with the installation.

There are options for fixing this issue. I personally don't care whether it ignores my empty drive(s) or interrogates me about my intention to put an install disk into one or more of them. The current implementation, which reports the issue but gives no guidance to the user regarding the next step, is a "sub-optimal" solution.

BTW, you can get rid of pyrun.exe if you get rid of a companion process with an unusual name such as py###.tmp.exe. If you are of a cautious nature, you might want to reboot after having done this.

I am a newbie at all of this. This is my first post. But I was having the same problem on my Vista computer. It has both a Drive E (a DVD/CD-RW drive) and a Drive F (DVD RW drive). I’d insert the Ubuntu 9.04 installation disc in Drive E and I would get the error message Windows no disk exception processing message, ditto if I put it in Drive F: By clicking on Continue a couple of times the screen with the three installation options comes up. Ok, on my XP machine with just a CD drive there was no problem. The installation screen with the three options came right up.

 I found this post on the web: http://itknowledgeexchange.techtarget.com/itanswers/windows-no-disk-exception-processing-message-c0000013/ It states:
“The event indicates that the server received an exception of STATUS_NO_MEDIA_IN_DEVICE (c0000013). The error occurs when the server tries to access a shared resource (for example, a CD-ROM or floppy disk) which has no media (that is, no disk) in the drive. To prevent these errors, insert a disk in the drive.”

I put a blank CD in my F drive, the Ubuntu CD in the E drive and no problem. The screen with the three installation options came up and no error message.

I posted an answer on 6/10/09 stating that when I put a blank CD in my 2nd DVD drive I did not get the exception error message. On trying to duplicate this, I again got an error message when putting the Ubuntu Live CD in disc drive 1, even though had put a disk in my 2nd drive. So I pulled the USB connection cable from my HP Photosmart D7160 printer which contains a card reader, essentially disconnecting my printer (with a card reader) from my computer; put the Ubuntu CD in my disc drive and no error message. So simply disconnecting my printer’s USB cable solved the problem for me. I tried this several times and no error message.

So in my case at least, it appears to be the card reader on my printer causing the problem. I must have had my printer disconnected (because I was trying everything I could think of) when I put the blank CD in my drive and erroneously thought I had solved the problem at that time by inserting the blank CD in my empty disc drive.

I am sorry for the confusion, but glad I have isolated the problem at least on my computer. I hope this might work for some of the others having this problem.

William Bass (webdunce) wrote :

@BB,

i also made several wrong guesses about what was causing the issue...i also installed blank CDs in my drives (lol)...then finally someone else pointed out the issue with card readers.

@others,
it appears that the wubi script is scanning all "drives" on the PC (windows treats card reader slots as drives on my machine) and is not able to deal elegantly with the card reader slots -- if they are empty.

i have 4 card reader slots and i have to click "continue" 12 times total (8 times at the beginning of the installation and 4 times somerewhere in the middle)...so that is 3 times per card reader slot. (all my card reader slots have normal ascii character names like drive M:).

WORKAROUNDS...
one can successfully install ubuntu by merely clicking thru the error messages 12 or so times OR by "ejecting" the card-reader (eject by right-clicking the card-reader's icon in the systray, then clicking on "safely remove hardware", then clicking on "stop")

SOME THOUGHTS ABOUT THE BUG (PROGRAMMING-WISE)...
i am not knowledgeable of python (i dabble in C#), but i did scan the python code and it seems to have some code that tries to check the letters A-Z to see if any of those letters are valid drives. I think that could be the source of the first 4 errors. Then i think i saw some code that scans all drives for an available ubuntu image...so that's probably where the second set of 4 errors originates...i don't know about the last 4 times, though...i didn't look too far into the script. however, the wubi script itself may not be so much to blame as the underlying python libraries (i googled and googled and it seems hard to find documentation on python methods that allow access to system drive information on a windows machine)...but perhaps python provides a way to catch the error...kinda like a try-catch block in C#??? (again, i am not familiar with python...so i may be way off base). Could the errors somehow originate from the instantiation and/or use of the Drive class objects??? (just some thoughts)

unfortunately...
if one is not aware of the card reader issue, after clicking "continue" on the error message 3 or 4 times, one naturally feels the computer is in some kind of infinite loop. this could potentially cause first-time users to think the ubuntu installation program is defective (that's what i thought at first) or has some compatibility issue with their PC...when, in fact, they simply have empty card reader slots.

William Bass:

With regard to the "infinite loop" phenomenon, I have no card readers on my machine, but an empty virtual CD drive provided by Daemon Tools. The loop sent me through the message dozens of times rather than three times. The same thing happens if my actual DVD drive is empty.

The workaround for a Daemon Tools virtual drive and a physical CD/DVD drive is to mount an image in the drive or put a disc in the drive, respectively. (The image and disc were not Ubuntu.)

i did it this way and it works.

Still an issue on the current version of Wubi, on a clean install of Windows 7.

It does appears to relate to the presence of card readers in the PC (I have 4) - and with the proliferation of these in both printers and PCs, it's likely to be affecting many, many first-time Ubuntu users.

I personally had to click 'Continue' a total of 44 times before the Wubi splash screen appears. Without having read this bug report, I'd probably have given up long before then :)

Adding an extract from the log file - if the developers need further information, let me know.

After reading some of the above comments, I went to Disk Management and unassigned the drive letter from my card reader. When I tried Wubi again there were no errors.

This really needs fixing as Wubi is meant to be an easy way for people to try Ubuntu and scary dialogs are likely to make a lot of people give up right there.

I am also getting the Exception Error dialog with a USB card reader plugged in.

Before clicking Continue each time, I waited a minute to leave a gap in the log timestamps to see if that would give any useful information.

I've attached the log and you can see that there are gaps before "DEBUG WindowsBackend: drive=Drive(G: removable 0.0 mb free )" and the same for drive K which are the empty card reader slots and again between "CommonBackend: Searching ISOs on USB devices" and "CommonBackend: Searching for local CDs".

My configuration is : C: & D: Hard Disk, E: cd with LiveCD mounted F: cdr empty. G: empty card read slot, I: & J: card reader slots with cards mounted, K: empty card reader slot ( Not sure what has happened to H: !)

Ray Folwell (ray-folwell) wrote :

I think that I have isolated where in the wubi code these dialogs pop up.
The first set are when GetDiskFreeSpaceExW is called at line 69 in backends/win32/drive.py. The second set are when glob.glob is called at line 650 in backends/common/backend.py

If it is a CD or USB card reader from which the media has been removed, you get the "Please insert disk message". If it is a card reader than has not had a card in since it was mounted, you get the Exception Error.

The solution might be to check filesystem in the __init__ method of Drive and set type = None if filesystem is blank.
I attach a patch that does that (patch at lines 43-50)

Hi Ray,

How interesting, just yesterday I also sent an idea for a patch via email to Agostino Russo. I didn't even notice the patch system here. Thanks for bringing that to my attention.

I looked at your patch, but just to let you know -- for me, at least -- get_filesystem() also causes the error for me GetVolumeInformationA method is the culprit in that one).

I have recommended that he use ctypes.windll.kernel32.SetErrorMode(1) at the beginning of the Drive class's __init__() to suppress the pop-up and ctypes.windll.kernel32.SetErrorMode(0) at the end to return windows back to the default state (regarding this pop-up, at least)...

Hi William,

It's interesting that you get the error on get_filesystem as well. That would explain why you get the message 3 times for each drive and I get it 2 times. Maybe itt is dependent on WIndows version? I'm XP Home SP3.

I am not familiar with the Windows API, but googling SetErrorMode suggests that this is the recommended way to avoid these messages.

I think you would still need to do something to avoid the message on the call to glob. You could wrap SetErrorMode calls round that, but the call in a common routine rather than windows, so I'm not sure of the implications of doing that.
Alternatively, you could set type=None if filesystem == "" in Drive

Ray,

I don't know windows api either. I found SetErrorMode after literally hours and hours of googling. Also, it needs to be clear...I have no experience in Python at all...except to try to figure out the Wubi code.

Also, you raise a good point, I seem to recall getting this error during installation, too. So, turning the message off just during Drive instantiation is probably not going to prevent all cases of this message.

In that case, I guess the script is calling methods on Drive objects somewhere else? So the SetErrorMode should be incorporated directly in the Drive methods causing the problem (get_space and get_filesystem).

However, then there is the glob.glob(path) issue that Ray Folwell found, and I see some calls to os.path.exists() in the code, too. I have confirmed taht os.path.exists() can raise the error IF it is called on an empty drive (I cannot tell if wubi code ever calls os.path.exists() on empty drives, though...but the potential seems to be there).

I recommend something else, in this case....

Somewhere in the Wubi code, there needs to be a function like so....

    def perform_disk_operation(disk_operation, *args):
        ctypes.windll.kernel32.SetErrorMode(1) # turn off no disk error
        retval = disk_operation(*args)
        ctypes.windll.kernel32.SetErrorMode(0) # restore no disk error to default mode
        return retval

Calls to the above function would actually pass in the desired function and arguments for that functions. For example...

    def get_space(self):
        drive_path = self.path
        freeuser = ctypes.c_int64()
        total = ctypes.c_int64()
        free = ctypes.c_int64()
        perform_disk_operation(ctypes.windll.kernel32.GetDiskFreeSpaceExW,
                unicode(drive_path),
                ctypes.byref(freeuser),
                ctypes.byref(total),
                ctypes.byref(free)) # FYI, returns 0 if unsuccessful...which could be
                                           # stored in a variable like so: is_successful = perform_disk_operation(....
        return total.value, freeuser.value

I don't know enough about Python to know if self needs to be an argument in the function or not {i.e., perform_disk_operation(self, disk_operation, *args): ???}, but I am envisioning a static method (does Python have those?) accessible from anywhere...perhaps in the Drive class....Drive.perform_disk_operation().

If Python doesn't support static methods, then a Disk_Manager or WubiUtilities object class could be created and instantiated and it could be used mainly for these sorts of things.

utilities = WubiUtilities
utilities.perform_disk_operation(xxx, yyy, zzz, ddd)

-----------------

Alternately (and I don't know how recommended this would be), SetErrorMode(1) could be called at the very beginning of the wubi execution and SetErrorMode(0) when wubi terminates. That would put the error mode in a non-default state while wubi is executing, and I don't know if that could cause potential problems in other windows processes or not (seems doubtful, though). It should be really easy to implement though and should prevent the pop-up the whole time (unless other windows processes are ...

I would normally prefer to turn something like this off for a short a time as possible, but it is worth noting that the Microsoft documentation at http://msdn.microsoft.com/en-us/library/ms680621%28VS.85%29.aspx says

"Best practice is that all applications call the process-wide SetErrorMode function with a parameter of SEM_FAILCRITICALERRORS at startup. This is to prevent error mode dialogs from hanging the application."
(SEM_FAILCRITICALERRORS is a constant value 0x0001)

That might be the simplest solution to implement.

William Bass (webdunce) wrote :

Hey Ray,

Excellent catch...that "best practice" thing. I glanced at the article when I first discovered SetErrorMode() and totally missed that important info.

Not only that, but I get the idea that it is setting the error mode only for that application...in deed, maybe even only for the particular thread it's called in. So, I think it can be turned off at start up and then there is no reason to even set it back to default before termination.

I opened up two command prompts and ran get_space() on one without calling SetErrorMode() at all and another that called only SetErrorMode(1) ... and never SetErrorMode(0). The command prompt window that didn't call it got the pop-up every time I ran it. The other did not....no matter that I ran the one that turned off the pop-up first...so it should have zero impact on other apps or processes.

That makes the answer clear to me...call ctypes.windll.kernel32.SetErrorMode(1) at start up and forget about it...unless there are other threads that could raise the error (I think I did see code that indicated wubi had more than one thread), then they all would need to call it as well before they were started.

By clicking through the error message several time the installer started
and now I'm a happy camper as Ubuntu 11.04 is installed and running. I
updated to 11.10 and found that it is not user friendly for me. I
un-installed the 11.10 version and re-installed 11.04 which is clear, clean
and works very nice.

After looking at the resolution (from a user not anyone from Canonical) I realized it was WUBI looking at one of my USB fobs as a hard drive. The only 2 USB fobs I had plugged in were for my web camera and my Logitech wireless mouse.
