Public bug reported: I am / was running Kubuntu 14.04.3 with the Kubuntu PPA and the backports PPA enabled. When I wanted to upgrade Kubuntu to 15.10, via 15.04 through Muon, the upgrade process did not complete due to unsolved dependencies. I have attached my full /var/log/dist-upgrade
Examining the dependency issues did not reveal any single culprit to me, but instead a pretty bad overall picture. Thinking that it might have to do with the two PPAs, I tried ppa-purge on them, but the dependencies during purge were broken, so no package could actually be removed. I therefore thought to bite the bullet and leave the two PPAs enabled and upgrade manually to 15.10 via sed -i 's/trusty/wily/g' over all the sources list. Who'd have thought.. this does not work and I ended up (after apt-get update ; apt-get dist-upgrade) in a big web of not working *configurations* of packages due to funny versions. I started working on those configurations, tackling things one by one (Apparmor syntax issues, for example here https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=763673) and sometimes dpkg -r <package>; apt-get download <package>; dpkg -i <package.deb> to force the issue. That seems to have worked to an extend where I managed to get all packages configured, but still the overall dependency web is broken. >From what I can gather, several packages depend on the old versions (perl etc), but their new versions would not. Now.. I do not feel like manually forcing the packages to upgrade, and it seems that aptitudes dependency resolution does not find a magic solution after letting it run for quite a while. That leads me to believe that I will also not do a great job, manually. Will attach /var/log/dist-upgrade, /etc/apt/**list. Not sure what the issue really was, but I hope someone else has a better idea how to tackle this. I will move my old root away (LVM) and start a fresh install. ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Attachment added: "sources.list" https://bugs.launchpad.net/bugs/1538323/+attachment/4557139/+files/sources.list -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1538323 Title: Kubuntu 14.04.3 -> 15.10 upgrade is broken (PPAs enabled) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1538323/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
