Hello Mate,

I see that the debdiff you provided applies to Noble, but this bug is also marked as affecting Mantic. Could you provide an updated debdiff for the Mantic version? Thanks!

Hi @sergiodj,

I believe it was already uploaded, and is currently in the unapproved queue: https://launchpadlibrarian.net/697888277/mesa_23.2.1-1ubuntu3_23.2.1-1ubuntu3.1.diff.gz

The difference to noble is purely the version number being ubuntu3.1 instead of ubuntu4.

Hello Mate, or anyone else affected,

Accepted mesa into mantic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/mesa/23.2.1-1ubuntu3.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-mantic to verification-done-mantic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-mantic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

All autopkgtests for the newly accepted mesa (23.2.1-1ubuntu3.1) for mantic have finished running.
The following regressions have been reported in tests triggered by the package:

asymptote/2.86+ds-1 (armhf)
clutter-1.0/1.26.4+git2779b932+dfsg-5 (armhf)
freeglut/3.4.0-1 (armhf)
gle/3.1.0-10 (armhf)
glfw3/3.3.8-1 (armhf)
gtk+3.0/3.24.38-5ubuntu1 (armhf)
libcsfml/2.5-1.1 (armhf)
libsdl2/2.28.3+dfsg-2 (armhf)
mutter/45.0-3ubuntu3.1 (armhf)
njplot/2.4-9 (armhf)
vtk9/9.1.0+really9.1.0+dfsg2-7 (armhf)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!

The autopkgtest regression above are due to armhf autopkgtest runner faults. The tests have been re-triggered and should succeed.

Confirmed to fix VirGL graphics acceleration on my previously affected machine.

This bug was fixed in the package mesa - 23.2.1-1ubuntu3.1
