When trying to log in as root (with public key) to an Ubuntu 14.04 LTS box, the OpenSSH server will just say
Server refused public-key signature despite accepting key!
I have enabled root login by setting PermitRootLogin accordingly and have also restarted SSH with /etc/init.d/ssh restart.
I have also verified that this specific error would not occur if my key were wrong or not in /root/.ssh/authorized_keys.
Why can't I log in ?
Disclaimer: Yeah, I know that using a root account on Ubuntu is not the proper way to do it, but I was told to. Meh.
