[Bug 1940720] Re: package openssh-server 1:8.4p1-5ubuntu1.1 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 1

Something on your system already blocks the default SSH port which the
service will try to consume on install/update. You'd want to find what
owns this port and remove/reconfigure that - afterwards the openssh-
server should install/upgrade fine again.

You can find this process via:
  $ sudo ss -pl4 '( sport = :ssh )'

Thank you for your report.

This looks like a local configuration problem, rather than a bug in
Ubuntu.

You can find pointers to get help for this sort of problem here:
http://www.ubuntu.com/support/community

Since we use this bug tracker to track bugs in Ubuntu, rather than
configuration problems, I'm marking this bug as Invalid. This helps us
to focus on fixing bugs in Ubuntu.

If you believe that this is really a bug, then you may find it helpful
to read "How to report bugs effectively"
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful
if you would then provide a more complete description of the problem,
explain why you believe this is a bug in Ubuntu rather than a problem
specific to your system, and then change the bug status back to New.

** Changed in: openssh (Ubuntu)
       Status: New => Incomplete
