In comment #13 I said that creating /etc/update-manager/release- upgrades.d/DistUpgrade.cfg allowed me to work around the problem. It looks like this approach has at least one major problem:
On a system that has a variety of PPAs configured, if I do the aforementioned "AllowThirdParty = true" hack, these PPA sources all get rewritten to use precise instead of lucid. If any PPA no longer exists in Precise, the upgrade fails. The old behavior was smart enough to rewrite just the sources for the local mirror, and disable the rest. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/289952 Title: update-manager rewrites sources.list to only use official mirrors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/289952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
