Question

EDIT: Putting exactly what was done

I need to SSH localhost without password, the usual way of doing it (with public keys) do not work.

user@PC:~$ rm         


        

Answer 1

I encountered the same problem when running unit tests on Docker container(golang:1.13-alpine).

After sshd -Dd and ssh -vv root@localhost debugging, I found the reason:

User root not allowed because account is locked

So, we should unlock the account by passwd -u or set a password.
