Re: how to edit sshd_config?
There is no need to do this and it is a security risk.
I am logged in the ubuntu desktop as root user and dunno how to fix this.
Log in as a user with admin (sudo) privileges and type this to run gedit with admin rights.
You can also use the terminal and nano.
pkexec gedit /etc/ssh/sshd_config
sudo nano /etc/ssh/sshd_config
