I get the same crasher on that fresh artful -> Bionic install. The apport message is : debconf is unknown, or so, even if debconf package is installed.
I confirm that the only debconf.py installed is at: /usr/lib/python3/dist-packages/aptdaemon/debconf.py But aptdaemon is said 'unmaintained' and listed for removal: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1673258 So update-notifier needs to update its path installation asap. ** Changed in: update-notifier (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731334 Title: update-notifier-common upgrade :debconf.py not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1731334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
