Actually, we are missing a parallel to DistUpgrade.cfg.jammy named DistUpgrade.cfg.kinetic and DistUpgrade.cfg.lunar. As there needs to be a DistUpgrade.cfg for the release from which you are upgrading which says what release you can upgrade to (see [Sources]) among other things.
This all seems prone to breakage though. ** Changed in: ubuntu-release-upgrader (Ubuntu) Importance: Undecided => High ** Changed in: ubuntu-release-upgrader (Ubuntu) Status: Confirmed => Triaged ** Also affects: ubuntu-release-upgrader (Ubuntu Noble) Importance: Undecided Status: New ** Tags added: rls-nn-incoming -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2075969 Title: lunar/mantic releases unable to do-release-upgrade to jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2075969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
