[Test Plan] To reproduce the issue, use the annotated steps below. Confirmed working as a reproducer for Focal and Impish. Bionic appears to use a -data package instead of building the db on "apt update"
Notes: 1) The "ubuntu" user below is unprivileged, the result of the "adduser ubuntu" command being run and accepting defaults. 2) The "lck" and "ack" commands were randomly selected as commands that were unavailable on the default Ubuntu images used by LXD. # Confirm UMASK grep "^UMASK" /etc/login.defs # Set /etc/login.defs to umask 027 sed -i -e 's/^UMASK\t\t022/UMASK\t\t027/' /etc/login.defs # Confirm grep "^UMASK" /etc/login.defs # Log out and back in exit # Log back in # Force rebuild of DB rm -rf /var/lib/command-not-found/* apt update ls -lah /var/lib/command-not-found/ # Verify failure su - ubuntu lck ack exit ## END repro The failures expected to be seen when running the "lck" and "ack" commands are similar to: ubuntu@lp1953610-focal:~$ ack Sorry, command-not-found has crashed!
