It seems you already have some other ssh server (or something else on that port) running. 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 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1621925 Title: package openssh-server 1:7.2p2-4ubuntu2.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in openssh package in Ubuntu: Incomplete Bug description: I was trying to install openssh server and I got following error $ sudo apt-get install openssh-server Reading package lists...
