Public bug reported: We currently only disable PPA's prior to beginning a release upgrade and I wonder if it would be possible to actually purge the PPA's or at least list the PPA's and recommend (or demand) that the user purge all PPA's prior to performing the upgrade?
I think it would be preferable to refuse to proceed with the upgrade than to have it fail once the process has begun, eh? I learned with a little help that the following command lists all PPA's in use: for PPA_FILE in $(ls /etc/apt/sources.list.d/*.list); do egrep -v '^#|^ *$' ${PPA_FILE} | grep "ppa.launchpad.net" | cut -d "/" -f4-5; done Then it's fairly easy to use ppa-purge to return the OS to a fairly out- of-box state package-wise. I don't know however what would happen with previously used PPA's that may have been disabled even though packages installed and/or upgraded via that PPA are still in use on the system. Maybe just a harsh warning would suffice if made prominent enough? I know we like to limit pop-ups but sometimes they're just needed. This should be considered a "wish list" bug, but I've thought about this for a while and bug #1600495 convinced me it was worth the electronic ink to mention it. ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602052 Title: ubuntu-release-upgrader should offer to actually purge PPA's To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1602052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
