The fix works for me. It's relatively easy to check for yourself with Docker.
To reproduce the issue (version 20.04.4): docker run --rm ubuntu:focal bash -c 'export DEBIAN_FRONTEND=noninteractive && apt-get update && apt-get -y install --no-install-recommends command-not-found && apt-get update ; apt-cache policy command-not-found' To test the fix (version 20.04.5): docker run --rm ubuntu:focal bash -c 'echo "deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted main multiverse universe" > /etc/apt/sources.list.d/ubuntu-focal-proposed.list && export DEBIAN_FRONTEND=noninteractive && apt-get update && apt-get -y install --no-install-recommends command-not-found && apt-get update ; apt-cache policy command-not-found' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876034 Title: apt update crashes with "KeyError: 'suite'" in cnf-update-db if index compression is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/command-not-found/+bug/1876034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
