Public bug reported: I have started online update from 18.04 to 20.04. Distribution upgrade crash on the same error message "Nelze vypočítat přechod na vyšší verzi" I try translate this to "Can't count transition to higher version".
I remove all ppa repositories and installed software from this repositories (handbrake, ansible) ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubuntu-release-upgrader-core 1:18.04.38 ProcVersionSignature: Ubuntu 4.15.0-118.119-generic 4.15.18 Uname: Linux 4.15.0-118-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.17 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Tue Oct 13 00:48:06 2020 InstallationDate: Installed on 2019-02-02 (618 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=cs_CZ.UTF-8 SHELL=/bin/bash SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to bionic on 2020-10-12 (0 days ago) VarLogDistupgradeTermlog: ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic dist-upgrade third-party-packages wayland-session -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899542 Title: Upgrade to 20.04 crash with ppa info To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1899542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
