  * autopkgtest: do not allow qemu to be used on ppc64el (LP: #1992178)
    Almost every run on ppc64el takes 12 to 24 hours, so do this as a last
    resort to relieve pressure on autopkgtest infrastructure.

Hello Dan, or anyone else affected,

Accepted systemd into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/systemd/249.11-0ubuntu3.10 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 systemd (249.11-0ubuntu3.10) for jammy have finished running.
The following regressions have been reported in tests triggered by the package:

The verification of the Stable Release Update for systemd has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

The release of this SRU has been rolled back in jammy because of bug #2035406 which appears to be a regression introduced in the new version of systemd.

This bug was fixed in the package systemd - 249.11-0ubuntu3.10
