Public bug reported: I received a notification that a new dist release is available. During the upgrade process, it fails by telling me that may be caused by ppa sources.
## What I expected to happen I expected the upgrade to happen, or to tell me which package fails to upgrade/causes dependencies troubles. ## What happened instead The upgrade failed, telling me that may be due to some PPAs and to use ppa-purge. But my system "has lived", so I'm not sure on how to find the whole list of installed PPAs (some have been deleted from apt.sources.d in the meantime). --- $ lsb_release -rd Description: Ubuntu 18.04.5 LTS Release: 18.04 $ apt-cache policy ubuntu-release-upgrader* ubuntu-release-upgrader-qt: Installé : (aucun) Candidat : 1:18.04.42 Table de version : 1:18.04.42 500 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/universe amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/universe i386 Packages 1:18.04.17 500 500 http://fr.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic/universe i386 Packages ubuntu-release-upgrader-core: Installé : 1:18.04.42 Candidat : 1:18.04.42 Table de version : *** 1:18.04.42 500 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/main i386 Packages 100 /var/lib/dpkg/status 1:18.04.17 500 500 http://fr.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic/main i386 Packages ubuntu-release-upgrader-gtk: Installé : 1:18.04.42 Candidat : 1:18.04.42 Table de version : *** 1:18.04.42 500 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic-updates/main i386 Packages 100 /var/lib/dpkg/status 1:18.04.17 500 500 http://fr.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 500 http://fr.archive.ubuntu.com/ubuntu bionic/main i386 Packages ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubuntu-release-upgrader-core 1:18.04.42 ProcVersionSignature: Ubuntu 4.15.0-135.139-generic 4.15.18 Uname: Linux 4.15.0-135-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.23 Architecture: amd64 CrashDB: ubuntu Date: Thu Feb 11 11:04:49 2021 InstallationDate: Installed on 2018-01-29 (1108 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) PackageArchitecture: all SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to bionic on 2021-02-11 (0 days ago) ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic dist-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915389 Title: Release upgrade fails to apply To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1915389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
