Hello Balint, or anyone else affected, Accepted unattended-upgrades into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/unattended- upgrades/2.3ubuntu0.1 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- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. 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. ** Changed in: unattended-upgrades (Ubuntu Focal) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1877769 Title: [SRU] Rewinding cache triggers obsolete adjustments consuming a lot of CPU Status in unattended-upgrades package in Ubuntu: Fix Released Status in unattended-upgrades source package in Focal: Fix Committed Status in unattended-upgrades package in Debian: Fix Released Bug description: [Impact] * Unattended-upgrades consumes excessive amount of CPU when rewinding cache trying to mark packages to upgrade or install even when they are already marked to be upgraded or installed.
