I checked and apparently now_auto_removable and pkgs_auto_removable are always the same, as "is_auto_removable" only returns different results _after_ the packages have actually been upgraded. Just marking them does apparently not change the output of is_auto_removable(). I tried to use the ProblemResolver but I didn't get the output of is_auto_removable() to change.
One possible solution is to actually upgrade the packages and then check for autoremovability, then you can make it works as intended. My original patch implemented only an autoremove (same as "apt-get autoremove"). -- 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/1267059 Title: "Unattended-Upgrade::Remove-Unused-Dependencies" does not work Status in “unattended-upgrades” package in Ubuntu: Triaged Bug description: I have a system that runs unattended-upgrades just fine.
