![]() So, my one and only user no longer has admin privs and/or cannot access sudo because of this file. Unfortunately I forgot to include the ‘admin’ group in the -g list, thereby (and I am assuming here) I was removed (?) from the sudoers file. So, here’s the deal: I did a moduser and changed my groups. Having personally worked with Unix for over 25 years, I find my situation infuriating to say the least. Let me say this: This assumption that Ubuntu makes in limiting access using what amounts of vague commands to the novice user is redundant, as the novice user doesn’t know anything about the vague commands of Unix, Linux, etc. Please support the nixCraft with a PayPal donation or Patreon.īelieve it or not, this is a rather annoying issue.

Now you can set up the root user password by typing the following command: Type your own password when prompted, and then you will see # prompt. But, I still want to set up a root password on Ubuntu. This means that in the terminal you should use sudo for commands that require root privileges simply prepend sudo to all the commands you need to run as root. This is where sudo comes in – it allows authorized users to run certain programs as root without having to know the root password. However, since the root account physically exists it is still possible to run programs with root-level privileges. This means that you cannot login as root directly or use the su command to become the root user.

To run all administrative command use the sudo command on Ubuntu. Therefore, you cannot log in as root or use ‘su -‘ command to become a superuser.
