I can't ssh with root or setup keys properly
I was trying to following this tutorial about ssh keys and security, but the server kept me asking password for the user.
So I tried to do it with the root,(to follow the tutorial integrally) Since I had disable the root for remote login (PermitRootlogin No), I tried to re-enable it but it doesn’t me allow to ssh with the root. so I have this problem and I don’t know were to look (logs or errors).
I can sudo and su - without problems and I login trough ssh with a created user. I did “sudo systemctl reload sshd.service” and rebooted after changing (PermitRootlogin yes) with no avail, I simply can’t ssh with root nor I can setup the keys for the user right.
