How to create an admin account after my admin account got deleted

Question

My admin account has been deleted.

This was because I had to use the dell recovery after a problem after one of the updates provided by Ubuntu.

Now I only have the guest account.

How do I go about creating a admin account for my Ubuntu system?.

Answer 1

First add a user name through this command

adduser <username>

You can then add a user to the sudo group with with the command:

sudo adduser <username> sudo

Note that versions of Ubuntu until 11.10 will use admin as group instead of sudo
