** Tags added: apport-collected dist-upgrade wayland-session ** Description changed: During upgrade to 26.04, the zfs key load unit was renamed from zfs- load-key-rpool.service to [email protected]. When another package (probabaly tpm-udev) postinst ran `systemctl daemon-reload`, that triggered systemd to tear down everything bound to the inactive unit including my interactive session. (AI used to help with the diagnosis) I was able to recover from the terminal by running `sudo-rs dpkg --continue -a`, the upgrade also renamed the sudo command, which was not very helpful. 1. Journal: old unit name was active at boot Source: journalctl -b 708732e878724076af5f58669bf97b65 (the boot the upgrade ran in; currently -b -1).
