Public bug reported: I just updated from Artful to Bionic using the usual GUI. Before upgrade, I had artful-proposed in sources.list, with a /etc/apt/preferences.d/proposed-updates pin as follows:
Package: * Pin: release a=artful-proposed Pin-Priority: 400 This pin is recommended in https://wiki.ubuntu.com/Testing/EnableProposed. I forgot I had this here. I've ended up with Bionic installed, but fully upgraded up to proposed. The preferences file wasn't touched, and since it is release-specific, it now has no effect. Could you perhaps detect if the proposed pocket appears in sources.list or sources.list.d and disable it like you do PPAs before upgrade? ** 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/1784165 Title: Upgrader leaves proposed pocket enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1784165/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
