Status: New
** 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.
+ During upgrade to 26.04, my interactive session died mid-upgrade and I

+ Possible cause: 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.
