warty-final-ubuntu.png is actually a JPEG file

Thank you for your bug report. I can confirm this on up-to-date Intrepid

chr1s@chris-desktop:~$ apt-cache policy ubuntu-wallpapers

This is not a problem for actually using it as a wallpaper (as remarked in the changelog for 0.28.1, Gnome will figure it out anyway) but you cannot open the image in eog (called "Image Viewer" in the UI). Perhaps this should be reported as a bug against eog but a symptom is that you cannot double-click on warty-final-ubuntu.png in /usr/share/backgrounds in Nautilus; the error message is "Could not load image 'warty-final-ubuntu.png'. Fatal error reading PNG image file: Not a PNG file".

Whatever the analysis, it seems misdirected to use an incorrect extension, and this should be easy enough to fix. (Also the base name "warty-final" is peculiar at best.)

I've uploaded a patch for this bug on my PPA:
https://launchpad.net/~flimm/+archive?field.name_filter=ubuntu-wallpapers&field.status_filter=any
(ubuntu-wallpapers_0.28.1-0ubuntu1)

Perhaps it could be changed to intrepid-final.jpg while you're at it, or something which does not mention a particular release.

Done, renamed to intrepid-final-ubuntu.jpg
(ubuntu-wallpapers_0.28.1-0ubuntu2)

I'm attaching the patch so that it will show up to those searching for user submitted patches. It's still available in my PPA.

Hi,

Thanks for submitting a patch! You should check out https://wiki.ubuntu.com/SponsorshipProcess to see the process for having your patch uploaded.

Also, a note on your patch. I'm not positive, but I believe that the wallpaper is still referred to a warty-final on purpose in order to automatically upgrade the default wallpaper when the user does a dist-upgrade. Someone from the artwork team should comment...

the reason for this file being named thusly is historical and due to the update process. It was intentionally done this way because the update process currently cannot handle different file types for the wallpaper. This is something that should be fixed in Jaunty.

Which project/package would be responsible for the update process, Kenneth? Is it update-manager? Do you know if a bug has been filed there concerning this issue?

And ++ for comment 4, but see comments 8,9. If you need a file to update, change the name once and make that stick. Using an obsolete name is confusing and annoying. See also LP bug 362526.

Just use imagemagick to convert the file..

the issue is that the name is used in users configurations so renaming would break upgrades

@Sebastien: Can't we rename it and make "warty-final-ubuntu.png" a symlink?

Therefore Mohamed said "Symlink".
a simple

mv warty-final-ubuntu.png ubuntu-default-wallpaper.jpg
ln -s ubuntu-default-wallpaper.jpg warty-final-ubuntu.png

and include the "warty-final-ubuntu.png" symlink in a separate upgrade transition .deb

Hey, you're doing a whole (great!) OS, fixing this bug can't be a real problem, can it?

A better solution would be to make it an actual PNG. On my color calibrated monitor I can see blocky JPEG actifacts.

Is the uncompressed version available anywhere?

Tobias: yes, Otto Greenslade has the originals. The choice of PNG/JPEG and compression size depends on what amount of space is available on the CD and the style of the image. For instance, if the next version of the default wallpaper was a piece of line-art, then it be more efficient to store it as a PNG.

So, it’s on his hard drive and not anywhere on launchpad?

Designers always seem to get special treatment.

Hm. Again - this bug is present since 2 1/2 years, and not substantly fixed despite beeing a beginner's job, isn't it?
Maybe Ubuntu will have a default wallpaper in a format we don't know yet in future or a video.
What makes it so difficult writing it in a config file with the full file name, no matter what format it has?

<pseudo config code>

[Default Ubuntu Background]
wallpaper=/usr/share/backgrounds/blah.jpg

</pseudo config code>

So where is the problem? Using 2 years of bugtracking does not equate the effort to fix this bug, does it?
So what can I do to help you fix this once and for all time for 11.04, or at least 11.10?

I could understand if too much stuff already linked to the pic and therefore changing it would break all that. But the problem is that almost nothing can link to it because its broken format! And software is tweaked to each release individually anyway.

libunity-2d-private0 package creates a symlink to that picture:
/usr/share/unity-2d/warty-final-ubuntu.jpg

I have proposed a merge to ubuntu-wallpapers that should resolve this long bug which is overdue for a fix.

My merge was put on hold because there were some conflicts which I will go through and fix and resubmit.... This is on my shortlist of bugs to finish by the end of next week.

Is any progress there?..

I have a new merge proposal in that fixes the bug... my last proposal was broken a bit for some odd reason.

aacid,
look at the comment #28:
libunity-2d-private0 package creates a symlink to that picture:
/usr/share/unity-2d/warty-final-ubuntu.jpg

This bug is still there in Ubuntu quantal in this package version:

Package: ubuntu-wallpapers
Version: 0.35.2

The one in 12.04 is actually better then the one in 12.10. Please have a look at that one.

Why that JPEG picture named "warty-final-ubuntu.png"?
Is it a some sort of nostalgia for Ubuntu 4.10 Warty Warthog?
Shouldn't it be replaced with some more generic name at last?

I agree with Bob. Pehaps name it simply ubuntu.jpg Then links to it will not break with distribution upgrades.

The version of Precise (also called warty-final-ubuntu.png and also a JPEG) in ubuntu-wallpapers-0.34.1 is indeed of higher quality then the one in ubuntu-wallpapers-0.35.2 from Quantal. If you want a copy to improve your Quantal desktop, you can find it directly here http://img29.imageshack.us/img29/6749/wartyfinalubuntu.jpg

Please finally fix this bug its more than 4 years old now.
It's embarrassing that even this simple bug is still not fixed !
