[Bug 1750754] Re: package openssh-server 1:7.5p1-10ubuntu0.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[ChristianEhrhardt]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

On upgrading a service this service has to be restarted to pick up the fixes.
Rather rarely a real issue occurs that the newer version does e.g. fail with the formerly working configuration.
But most of the time what happens is, that a service was installed, but stays unconfigured or experimented with but left in a broken state.

Now on any update of the related packages that service has to be restarted, but since its config is incomplete/faulty it fails to restart.
Therefore the update of that package has to consider itself incomplete.

Depending on your particular case there are two solutions:
- either remove the offending package if you don't want to continue using it.
- Or if you do want to keep it please fix the configuration so that re-starting the service will work.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers
to get help for this sort of problem here:
http://www.ubuntu.com/support/community

Or 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
