[Bug 2078461] Re: package openssh-server 1:9.6p1-3ubuntu13.5 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 1

[Anders Wenhaug]

I was able to fix this by stopping `ssh.service` and `ssh.socket`. After
that the upgrade worked (by `apt upgrade`).

You should be able to stop both of those while still being connected (I
tested this afterwards to be sure) since sshd seems to fork a new
process that handles the connection. If you don't dare test this then I
suggest running an ssh server on the side (`sudo sshd -f <sshd_config>
-h /etc/ssh/ssh_host_rsa_key -D` - sshd_config should be a new config
where you at least change the listen port)
