Cannot install SSH.
The password for one of our user names wasn't allowing us to login. We changed the password, but had the issue again.
In attempt to fix this I reset the SSH. Now ssh will not reinstall.
When trying to re-install the server we get the following errors
"Openssh-server" has no installation candidate"
"Package openssh-server is not available, but is referred to by another package. This may mean the the package is missing, has been obsolete , or is only available from another source.
E: Unable to locate package ssh
E: Package 'openssh-server" has no installation candidate
