Hello Dimitri, or anyone else affected,

Accepted livecd-rootfs into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/livecd-rootfs/2.765.19 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.

  * Do not use the ubuntucinnamon-desktop task for cinnamon builds, it doesn't
    seem to be present in the archive yet. Use the metapackage instead, which
    seems like a better way forward anyway. For the live task, temporarily use
    a hard-coded list of packages.
  * Explicitly define the kernel flavor for ubuntucinnamon.
