I don't believe it has anything to do with non standard 3rd party apt sources. I had disabled all of them other than the bone stock ubuntu sources. Also I had no issue upgrading at all after i fixed the location of the servers to the archives. This is simply a complaint that there is no upgrade path other than manually changing repositories to the archives on a now unsupported release. It is bad human ergonomics :)
I did note that there was a bug in the updater with bug https://bugs.launchpad.net/bugs/1744722 I did not have any issues with upgrading once the source list servers info was corrected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1745754 Title: upgrading from an End of Life release is not easy peasy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1745754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
