I am having trouble installing OpenSSH server on Ubuntu Server 16.04.01 which is a virtual machine using KVM.
When I try to install openssh-server I get the following response:
Setting up openssh-server (1:7.2p2-4ubuntu2.1) ... Creating SSH2 RSA key; this may take some time ... 2048 SHA256:i6IKfykW1E9hYmlHFLid3KksBI11oxCmKlbQjFOVNZY root@host (RSA) Creating SSH2 DSA key; this may take some time ... 1024 SHA256:tGZN8I6qfTdAanbPy4fxj/ARLTPrrtQKWZXTQZWG/o4 root@host (DSA) Creating SSH2 ECDSA key; this may take some time ...key_generate failed dpkg: error processing package openssh-server (--configure): subprocess installed post-installation script returned error exit status 255 Processing triggers for systemd (229-4ubuntu7) ...

Errors were encountered while processing: openssh-server E: Sub-process /usr/bin/dpkg returned an error code (1)
Does anyone have any suggestions on how to overcome this problem?
