[kwlug-disc] I'm "not in sudoers file."

[Ronald Barnes]

Well, despite the time being 03:15, I decided to boot from live USB and 
fix it.

Done and done.

Therein lies the clue I overlooked: I added myself to the docker group 
erroneously and incorrectly.


usermod -G (--groups) to add user to new group(s) REQUIRES the -a 
(--append) option if one is not willing to manually specify all the 
groups the user is to be in as arguments to usermod.

Apparently, it keeps you in your default group that matches your 
username though.


Can't believe I blew it on that.


Anyone have a handy list of the default groups for a normal user on 
Ubuntu 16.04?

Thanks everyone.
