I had the same problem at my machine. I tried to remove and then reinstall openssh-server, but the same error occurred. I know, that just remove openssh-server takes all my conf files on the system. I finally solved my problem by using sshd -t and get an error in my config file, which was running fine with previous version of openssh-server. It seems, that there is no more option to for roaming?
Comment out "UseRoaming no" fixed this issue for me. Perhaps you use this option in your old config file? -- 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/1579978 Title: upgrade to 1:7.2p2-4ubuntu1 fails on ubuntu server Status in openssh package in Ubuntu: New Bug description: This package upgrade failure has occurred on multiple machines, with the same error on each machine.
