package fglrx 2:8.723.1-0ubuntu2 failed to REMOVE: error exit status 2 - dpkg-divert: mismatch on package - while removing the package

I had the similar issue trying to remove the fglrx driver after the upgrate from 9.10 to 10.04 RC.

fglrx was installed in 9.10 (from ubuntu repo, of course), I've performed the upgrade, then I've tried to remove fglrx using jockey utility.

Trying to remove the package from command line, I've

Removing fglrx ...

thanks for your report.

it looks like bug 552782 but the later was failing in pre-installation script, now we are failing on post-removal script.

Can you still reproduce the problem?

Yes, the same error occurs while trying to remove it by aptitude and
apt-get

the command line gives (sorry its German):

dpkg-divert: Keine Übereinstimmung mit Paket

I'm sorry for updating the description, I didn't mean to. I just accidentally double clicked on the exclamation mark on the upper right.
But since I need to comment anyway: I can confirm niklas, the bug still exists for me as well.

I solved my problem by this solution
http://forum.ubuntuusers.de/topic/nach-upgrade-fglrx-laesst-sich-nicht-deinstal/2/#post-2468538

Basically by deleting the entries from this file "/var/lib/dpkg/diversions" (can be there more than one time)
/usr/lib/libGL.so.1.2
/usr/lib/fglrx/libGL.so.1.2.xlibmesa
xorg-driver-fglrx

than the removal works:

sudo apt-get --purge remove fglrx-kernel-source fglrx-modaliases xorg-driver-fglrx fglrx-amdcccle libamdxvba1

niklas' approach worked for me as well. fglrx now seems to be properly uninstalled and the free ati driver is working without any issues.
Compiz, 3D and KMS work, glxinfo |grep vendor gives
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: Advanced Micro Devices, Inc.

Though I think it's not neccessary to remove fglrx-modaliases since that package (as far as i understand it) exists to tell jockey on which cards the fglrx can be installed. I guess jockey won't work properly without it so it might be useful if you want to install fglrx via jockey sometime in the future. (Correct me if I'm wrong)

The workaround proposed by niklas in mex #7 *works* for me too: now i can uninstall fglrx.

Slightly neater work-around:

dpkg-divert --remove /usr/lib/libGL.so.1.2

I'm not quite sure if this will work for every setup. In my case the lines I had to remove have been in /usr/lib32/ so I guess the command would then be dpkg-divert --remove /usr/lib32/libgl.so.1.2 (I haven't tried it since I've edited var/lib/dpkg/diversions manually)
Platform: amd64

For me performing step #10:

dpkg-divert --remove /usr/lib/libGL.so.1.2

then apt-get remove steps from #7:

sudo apt-get --purge remove fglrx-kernel-source fglrx-modaliases xorg-driver-fglrx fglrx-amdcccle libamdxvba1

 worked fine

Jean-Baptiste,

Thanks for explaining how to remove the driver. Nevertheless, I decided to
move from Radeon HD 4670 to GeForce 210, I gonna install that to my computer
once the fglrx is fully removed.

Best Regards,

Jérôme Rioublanc

Specs of my fully updated Lucid 64 Bit:

- Sony Vaio FW4
- ATI Mobility Radeon HD 4650
- Linux linuropa 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux
... with Gnome and newest fglrx from ATI homepage.

This (slightly different) workaround solved my problem. Notice the different path in the first command (lib32 instead of lib):

$ sudo dpkg-divert --remove /usr/lib32/libGL.so.1.2
$ sudo apt-get --purge remove fglrx-kernel-source fglrx-modaliases xorg-driver-fglrx fglrx-amdcccle libamdxvba1

Because of the fact that I had already installed the new fglrx driver from ATI homepage and just wanted to remove the "old remnant" (because of a brightness acpi/dsdt bug that sadly affected me since Lucid again), I did the following after entering the two command above - just to be sure:

### Re-installation of newest fglrx driver downloaded from ATI homepage
$ sudo ./ati-driver-installer-10-5-x86.x86_64.run
$ sudo aticonfig --initial -f
$ sudo init 6

Maybe this is useful to some ppl.
Thx for the workaround.

Dennis

All,

Many thanks for the workaround.
Works for me on VAIO VGN-FW21E (for reference)

cheers,

still happend just now when upgrading from 10.04 to 10.10 beta

On upgrade from 10.04 to 10.10 BETA I experienced the same, (I should have researched before jumping in to BETA)..

sudo dpkg-divert --remove /usr/lib32/libGL.so.1.2

Notice the /lib32 not /lib as I am running on a 64bit platform.

This seems to allow a purge to work but leaves some stale directories.

on maverick by uninstalling fglrx:

warning, in file '/var/lib/dpkg/available' near line 59385 package 'virtualbox-3.0':
 error in Version string '3.0.12-54655_Ubuntu_karmic': invalid character in revision number

 error in Version string '3.0.12-54655_Ubuntu_karmic': invalid character in revision number

The problem in my case seemed to be that the /var/lib/dpkg/info/fglrx.postrm script refered to...
  /usr/lib/libGL.so.1.2

... but should have referred to...
  /usr/lib/mesa/libGL.so.1.2

... in two places.

Changing those two enabled me to remove fglrx.

This bug was fixed in the package fglrx-installer - 2:8.801-0ubuntu1

---------------
fglrx-installer (2:8.801-0ubuntu1) natty; urgency=low

  * New upstream release 8.801 (10-12).
  * debian/control:
    - Add Vcs-Git and Vcs-Browser.
  * debian/fglrx.postrm:
    - Do not remove diversions. Those diversions were likely installed by older
      releases of the driver (since we don't use diversions any more). Any
      diversion should be removed in fglrx.preinst, as it's exactly where we
      remove all other diversions (LP: #566437).
  * debian/fglrx.prerm:
    - Call dpkg-trigger with --by-package=$PACKAGE_NAME.
  * Add support for blacklisting card ids from GRUB gfxpayload=keep:
    - In Natty gfxpayload=keep is set by default so as to provide a framebuffer
      early in the boot process. Some cards don't play nicely with it, therefore
      we need to blacklist them in a file. The format is a sequence of lines of
      the following form:
        vVENDORdDEVICEsvSUBVENDORsdSUBDEVICEbcBASECLASSscSUBCLASS
      Blacklist lines are regex-matched against a corresponding PCI ID string.
      In practice this means that you can replace any part of the ID string
      with .* to match anything.

Just happened to me as well when upgrading from 10.04 to 10.10:
I fixed it with
sudo dpkg-divert --remove /usr/lib/libGL.so.1.2
sudo dpkg-divert --remove /usr/lib32/libGL.so.1.2
sudo apt-get purge fglrx

@Alberto and others: May I suggest a SRU (Stable Release Update) to 10.10 Maverick and/or 10.04 Lucid to save the (non-technical) users that have not yet upgraded from 10.04 to 10.10 from a bad user-experience.

Please...

Status changed to 'Confirmed' because the bug affects multiple users.

Alberto, this is targetted for 10.04.4. Can this fix easily be backported to lucid? If not, we should just drop the milestone. Thanks!

I've just uploaded fglrx-installer 2:8.723.1-0ubuntu6 in lucid-proposed which contains both the fix for this bug and the other correction for dpkg-trigger from 2:8.801-0ubuntu1.

Hello Marco, or anyone else affected,

Accepted fglrx-installer into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Could anyone please try the packages in lucid-proposed and confirm that they still work as intended? Would be good to get them into 10.04.4.

SRU verification for Lucid:
I have reproduced the problem with fglrx 2:8.723.1-0ubuntu5 in lucid-updates and have verified that the version of fglrx 2:8.723.1-0ubuntu6 in -proposed fixes the issue.

Marking as verification-done

This bug was fixed in the package fglrx-installer - 2:8.723.1-0ubuntu6
