Comment 11 for bug 1961640

I tested with subiquity from edge:
root@ubuntu-server:/# snap list subiquity
Name Version Rev Tracking Publisher Notes
subiquity 22.02.2 3120 latest/edge canonical* classic
and it seems to work now.

I was able to complete a complete default installation, incl. post-install reboot and login:
ubuntu@gulpin:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.4 LTS
Release: 20.04
Codename: focal
ubuntu@gulpin:~$ uname -r
5.4.0-100-generic
ubuntu@gulpin:~$ uptime
 07:50:35 up 2 min, 1 user, load average: 0.45, 0.21, 0.08

I shamelessly used a P8 system from patriciasd (gulpin) that was off anyway.

I can't try atm on P9, since there is no bare-metal available right now.

But generally I think subiquity 3120 fixed this.
