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 very small change fixes how call_checked() verifies that the package to be upgrades/installed is indeed marked to either being installed or upgraded. In the worst case, if call_checked() erroneously returns success for a package as a result of a regression, unattended-upgrades does not fall back to adjusting packages to make marking successful. Later unattended-upgrades finds out that the package could not be marked and should be treated as kept back.
