Public bug reported: I checked for broken packages and updated everything through apt.
When running sudo do-release-upgrade, it hangs after the second "Reading state information... done" after fetching packages, and then gives me Aborting Reading package lists... Done Building dependency tree Reading state information... Done Here is the main.log output: 2021-03-08 16:03:28,238 INFO Using config files '['./DistUpgrade.cfg.bionic']' 2021-03-08 16:03:28,238 INFO uname information: 'Linux sahil-Precision-Tower-79$ 2021-03-08 16:03:28,741 INFO apt version: '1.6.12ubuntu0.2' 2021-03-08 16:03:28,741 INFO python version: '3.6.9 (default, Jan 26 2021, 15:3$ [GCC 8.4.0]' 2021-03-08 16:03:28,746 INFO release-upgrader version '20.04.29' started 2021-03-08 16:03:28,757 INFO locale: 'en_US' 'UTF-8' 2021-03-08 16:03:28,824 INFO screen could not be run 2021-03-08 16:03:28,864 DEBUG Using 'DistUpgradeViewText' view 2021-03-08 16:03:28,924 DEBUG enable dpkg --force-overwrite 2021-03-08 16:03:28,973 DEBUG creating statefile: '/var/log/dist-upgrade/apt-cl$ 2021-03-08 16:03:32,763 DEBUG lsb-release: 'bionic' 2021-03-08 16:03:32,764 DEBUG _pythonSymlinkCheck run 2021-03-08 16:03:32,766 DEBUG openCache() 2021-03-08 16:03:32,766 DEBUG quirks: running PreCacheOpen 2021-03-08 16:03:32,767 DEBUG running Quirks.PreCacheOpen 2021-03-08 16:03:33,933 DEBUG Comparing 4.15.0-136 with 2021-03-08 16:03:33,934 DEBUG Comparing 4.15.0-50 with 4.15.0-136 2021-03-08 16:03:33,934 DEBUG Comparing 4.15.0-51 with 4.15.0-136 2021-03-08 16:03:33,934 DEBUG Comparing 4.15.0-52 with 4.15.0-1362021-03-08 16:03:34,187 DEBUG /openCache(), new cache size 102155 2021-03-08 16:03:34,187 DEBUG need_server_mode(): run in 'desktop' mode, (becau$ 2021-03-08 16:03:34,187 DEBUG checkViewDepends() 2021-03-08 16:03:34,188 DEBUG running doUpdate() (showErrors=False) 2021-03-08 16:03:36,933 DEBUG openCache() 2021-03-08 16:03:38,236 DEBUG Comparing 4.15.0-136 with 2021-03-08 16:03:38,237 DEBUG Comparing 4.15.0-50 with 4.15.0-136 2021-03-08 16:03:38,237 DEBUG Comparing 4.15.0-51 with 4.15.0-136 2021-03-08 16:03:38,237 DEBUG Comparing 4.15.0-52 with 4.15.0-136 2021-03-08 16:03:38,551 DEBUG /openCache(), new cache size 102155 2021-03-08 16:03:38,552 DEBUG doPostInitialUpdate 2021-03-08 16:03:38,552 DEBUG quirks: running focalPostInitialUpdate 2021-03-08 16:03:38,552 DEBUG running Quirks.focalPostInitialUpdate 2021-03-08 16:05:39,529 DEBUG abort called 2021-03-08 16:05:39,530 DEBUG openCache() 2021-03-08 16:05:40,757 DEBUG Comparing 4.15.0-136 with 2021-03-08 16:05:40,758 DEBUG Comparing 4.15.0-50 with 4.15.0-136 2021-03-08 16:05:40,758 DEBUG Comparing 4.15.0-51 with 4.15.0-136 2021-03-08 16:05:40,758 DEBUG Comparing 4.15.0-52 with 4.15.0-136 2021-03-08 16:05:41,022 DEBUG /openCache(), new cache size 102155 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubuntu-release-upgrader-core 1:18.04.42 ProcVersionSignature: Ubuntu 4.15.0-136.140-generic 4.15.18 Uname: Linux 4.15.0-136-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.9-0ubuntu7.23 Architecture: amd64 CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Mon Mar 8 15:50:00 2021 InstallationDate: Installed on 2018-11-07 (852 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: ubuntu-release-upgrader UpgradeStatus: Upgraded to bionic on 2021-03-08 (0 days ago) VarLogDistupgradeAptlog: Log time: 2021-03-08 15:10:03.838970 Log time: 2021-03-08 15:10:07.843096 Log time: 2021-03-08 15:12:10.311055 ** 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/1918208 Title: failed upgrade from 18.04 to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1918208/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
