Public bug reported: When I try to upgrade to kubuntu 16.04, I get the error: There was a fatal error in the planning of the upgrade
This can be because of: - Upgrading to an unfinished version (obviously not, since 16.04 has been released) - Running an unfinished version (No, I am running 15.10) - Are dependent of unofficial packages that are not supported by ubuntu (Not sure, but I can't find any) I thought it was because of cinnamon that I had installed, but I get the same error after I removed it. And I used sudo apt-get autoremove after I removed it. Restarted as well. I have no clue why I can't upgrade. I have searched the net for similar problems, but could not find any other similar cases. I guess that I have 1 or more package installed that blocks the upgrade, but as I said, I have no clue which one(s). I hope someone here can find the problematic package, and let me know which one it is. Other weird thing is, I do not have ubuntu installed. After I got rid of cinnamon, the only ones left are kubuntu and ubuntu mate. Side-note, probably not the cause (but never know) I have Windows 10 installed as well. If this is not a bug, please let me know. But please let me know how to fix this. This is so weird, I do not have ubuntu installed but that is the readout I get when using lsb_release -rd Description: Ubuntu 15.10 Release: 15.10 ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: ubuntu-release-upgrader-core 1:15.10.14.4 ProcVersionSignature: Ubuntu 4.2.0-36.42-generic 4.2.8-ckt8 Uname: Linux 4.2.0-36-generic x86_64 ApportVersion: 2.19.1-0ubuntu5 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: KDE Date: Sat Jun 4 08:34:44 2016 InstallationDate: Installed on 2015-04-29 (401 days ago) InstallationMedia: Kubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) PackageArchitecture: all SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to wily on 2016-06-04 (0 days ago) ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug dist-upgrade third-party-packages wily -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589047 Title: Error upgrading to 16.04 Error during planing to upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1589047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
