Public bug reported: after an 'apt dist-upgrade' and an 'do-release-upgrade' i get this error:
Could not calculate 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. probably my problem is one of the 3 listed but there is no help to solve the problem... many thanks, Michele ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: ubuntu-release-upgrader-core 1:17.04.10 ProcVersionSignature: Ubuntu 4.10.0-37.41-generic 4.10.17 Uname: Linux 4.10.0-37-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.4-0ubuntu4.5 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: GNOME Date: Wed Nov 1 16:36:36 2017 InstallationDate: Installed on 2017-07-03 (120 days ago) InstallationMedia: Ubuntu 17.04 "Zesty Zapus" - Release amd64 (20170412) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=it_IT.UTF-8 SHELL=/bin/bash SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to zesty on 2017-11-01 (0 days ago) ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug dist-upgrade zesty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1729378 Title: impossible to upgrade ubuntu from 17.04 to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1729378/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
