@sabdfl How was dpkg started? As root systemctl should not ask for password.
@stolowski The snapd version seems to be a git snapshot, not one from the archive. Marking as invalid for dpkg and systemd because nothing shows that there would be any issue with their behaviour. Please reopen the bug against one of them if the root cause seem to be in them. ** Changed in: systemd (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1868706 Title: Snapd postinst script hangs Status in snapd: Triaged Status in dpkg package in Ubuntu: Invalid Status in systemd package in Ubuntu: Invalid Bug description: On a machine which has been tracking upgrades for a while, I am unable to install new versions of snapd.
