11.10 has allowed me to (stupidly) remove my admin level login leaving me with only my standard log in. I am no longer able to modify any software, update etc.
How can I 'uprate' my user login back up to admin level?
Follow any of the procedures for resetting a forgotten password (or this, this, or this), but do not run:
usermod -a -G sudo username
username should be replaced with your actual username.
Note: if you are on Ubuntu 11.10 or an older release, the command to run is:
usermod -a -G admin username
On Ubuntu 10.10
admin group was not enough after creating the new user with
adduser username. I also had to make the user memeber of the
usermod -a -G admin,sudo username
