Public bug reported: Description: Ubuntu 18.04.4 LTS Release: 18.04 Error message says This was probably caused by: * Unofficial software packages not published by Ubuntu Use the "ppa-purge" tool from the ppa-purge package to remove software from a Launchpad PPA and try to upgrade again.
I am trying to upgrade to new LTS using terminal command update-manager -d I've installed ppa-purge and tried using it but I can't seem to figure out which to package to remove. I've tried looking in the logs but the issue "escapes" me Regards, Simon ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubuntu-release-upgrader-core 1:18.04.37 ProcVersionSignature: Ubuntu 4.15.0-99.100-generic 4.15.18 Uname: Linux 4.15.0-99-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.14 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Sat May 9 18:25:31 2020 InstallationDate: Installed on 2016-06-02 (1437 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) PackageArchitecture: all SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to bionic on 2020-05-09 (0 days ago) VarLogDistupgradeTermlog: ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic dist-upgrade third-party-packages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877761 Title: Upgrading to new LTS 20 from LTS 18 via command update-manager -d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1877761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
