After an update a few weeks ago, I'm noticing that my user was removed from the sudoer list. I'm not sure why, it's the only user on the system. Seems like it might have something to do with the change over from the software center to discover.
I haven't found a solution from the forums yet but also being cautious not to run something that will break the system.
Can anyone let me know a safe method for adding my username back into the sudoer file?
