Ubuntu 16.04 Root User not found

@scottalanmiller said in Ubuntu 16.04 Root User not found:

Ubuntu does not use a root user by default.

Scott the trouble (as I understand it) is that even the user he created doesn't have root access.

Appears to be a corrupt sudoers file, take a look at the following link.

@tiagom ssh server is conifugured in it.port 22 is taken from #

scottalanmiller

On Ubuntu run.... netstat -tulpn to see if port 22 is listening.

Might need to boot into single user mode and fix /etc/sudoers from there.
