failed to install ca-certificates-java in ppc64le systems: fatal: Tried to call a TRAP

According to the upstream discussion, this issue should have been fixed by merged commit https://gitlab.com/qemu-project/qemu/-/commit/083fe9a12d2025bb719ce8fb8cef86266f9bdddd and https://gitlab.com/qemu-project/qemu/-/commit/62089c849d49f92823c68624720cdac8fa4b43e0.

This is supposed to be fixed in upstream version v7.0.0-rc0 or newer. Debian bookworm has 1:7.0+dfsg-7.

Test builds available for jammy and kinetic in https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1980896

Attach proposed debdiff for jammy (6.2+dfsg-2ubuntu6.4) and kinetic
(6.2+dfsg-2ubuntu9). Need sponsor for uploading.

For Impish and older, it takes more prerequisite commits yet to be found and back ported.

FYI - I'm working on qemu 7.0 for Kinetic - consider this soon to be fixed there.
I'll add a bug reference to this bug to the changelog.

Thanks for the update.

Now that this completed in Kinetic, the PPA build being fine, and the patches & changelog being ok I think we can kick this off in Jammy.

Note: You do not need to list yourself twice in the changelog, that is only needed if multiple contributors added content - I fixed this up and sponsored that.

Note: especially with code that is architecture sensitive - like qemu - I recommend next time to enable more than just amd64 in the test PPA.

=> Reviewed and Sponsored to Jammy.
Please help with the verification once accepted by the SRU team.

Hello You-Sheng, or anyone else affected,

Accepted qemu into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:6.2+dfsg-2ubuntu6.4 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-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. 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 qemu (1:6.2+dfsg-2ubuntu6.4) for jammy have finished running.
The following regressions have been reported in tests triggered by the package:

systemd/unknown (s390x)

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

[1] https://wiki.ubuntu.com/StableReleaseUpdates#Autopkgtest_Regressions

Thank you!

FYI: the autopkgtests have been flaky and are good now.

@You-Sheng Yang - will you please do the verification so that this can move to Jammy?
I'd have another SRU in the queue which is waiting for this one to complete.

That Unknown privilege violation still exists, but no longer a fatal failure to qemu. Verified.

bionic has reached the end of standard support and is now supported only for security fixes via Ubuntu ESM (Extended Security Maintenance). I'm therefore closing the bionic task as wontfix.

ubuntu-sponsors is subscribed to this bug report, and there is an open task on focal which is a potential candidate for SRUing, but there is no patch against qemu 4.2-3 attached to this bug. I am unsubscribing ubuntu-sponsors. If you want this SRUed to focal and prepare a corresponding patch, please subscribe ubuntu-sponsors again.
