The MediaWiki package intentionally doesn't run the updater. You can either use the web updater (http://localhost/mediawiki/mw-config/) or the command-line updater (/usr/share/mediawiki/maintenance/update.php).
This is also documented in the package's README.Debian and in the package's NEWS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890197 Title: mediawiki schema issue after do-release-upgrade -d from 18.04 to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mediawiki/+bug/1890197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
