Public bug reported: Could not determine the upgrade
An unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. I have made minimal changes to the OS, and only installed a few things, I wonder why it won't do a simple upgrade ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: ubuntu-release-upgrader-core 1:0.190.8 ProcVersionSignature: Ubuntu 3.7.0-7.15-generic 3.7.0 Uname: Linux 3.7.0-7-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.6.1-0ubuntu13 Architecture: amd64 Date: Tue Mar 11 22:45:16 2014 InstallationDate: Installed on 2012-03-27 (714 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Beta amd64 (20120327.1) MarkForUpload: True PackageArchitecture: all SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to quantal on 2014-03-11 (0 days ago) VarLogDistupgradeTermlog: ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug dist-upgrade quantal running-unity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291089 Title: cant upgrade from 12.10 to 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1291089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
