[Bug 1993478] Re: package openssh-server 1:9.0p1-1ubuntu7 failed to install/upgrade: postinstall script returned 1

[Christophe M.]

It is exactly the same issue msaxl reported, the Opensshd returns an
error 1 at the ends of the upgrade process, and after the upgrade it is
impossible to bind/listen opensshd on anything else than :::22.

The first issue which is that opensshd reported an error 1 at the end of
the upgrade process, happened on one machine.

I'll open a ticket for the bind/port issue as msaxl isn't really clear
with what he said regarding the behavior of Opensshd post-upgrade, and I
understood only because I had the exact same issue.

The second that is about the sshd.socket, or whatever it is, unit that
doesn't allow opensshd to listen or bind to anything other than :::22.
In short it is impossible to bind or listen to a custom port with
Opensshd after upgrading 22.04 to 22.10 on both of my machines. The
machine that returned an error 1 and the other that didn't. Same as
msaxl

That second issue that msaxl reported happens to me on both of my
machine, including the machine that did not report an opensshd error 1
at the end of the upgrade process.

I joined the log from the machine that had the opensshd error 1
