Solved the ssh login taking 5 minutes, thanks to a power outage.
When logging back in - no motd.
When investigating that, found that update-motd wasn't completing.
When investigating why, found
/etc/update-motd.d/99-livepatch-kernel-upgrade runs /snap/bin/canonical...
And, I had snapd.service masked. Took 5 minutes to time-out.
systemctl umask snapd.service
systemctl enable --now snapd.service
with "UsePAM yes" in /etc/ssh/sshd_config
and login takes seconds again.
Weird, I don't remember masking snapd; it was probably quite a while ago.
