Updated from 15.04 to 15.10, SSH no longer works, but SFTP does

[Justin_Slay]

So this is a first for me. SSH is not working, but I can SFTP into the server over port 22.

Just did an upgrade over ssh to 15.10. Any suggestions?

I have checked the listenaddress in /etc/ssh/sshd_conf and :: and 0.0.0.0 are both uncommented.

Try:

ssh -vvv userid@IP
to see if there are any clear issues in the verbose connection data.

Update to the newest version of putty, same thing just happened to me. I think there was a security hole that got patched, so you need the newer client.
