[Bug 1851337] Re: package openssh-server 1:8.0p1-6build1 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 1

Hi csozo,

It looks like your system was under some form of memory pressure prior
to the openssh installation.  So I don't think this is a fault
necessarily in openssh itself but rather due to your computer having run
out of memory and gotten into some sort of inconsistent state.

I would recommend rebooting the machine (if you haven't already), and
running `apt-get -f install`.  It looks like there might have been some
reconfiguration questions (possibly updates to some of your manual
configuration work?) so I'd run it from a terminal window and keep an
eye on it.

Once you've done that, can you let us know if the issue is resolved or
if you get a better insight as to what went wrong?
