Thank you for the suggestion, especially for such a perfunctory bug report on my part. Unfortunately, the suggestion failed. do-release- upgrade still fails.
In detail, ppa-purge failed to remove the blender ppa. I did the following: removed blender, removed its repository with apt-add-repository -r, and reran do-release-upgrade. I still end up with the same problem I initially reported, or at least I end up with the same symptoms. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365076 Title: do-release-upgrade fails from 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1365076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
