I'm running Ubuntu Server 11.04. It came time to add User to the sudoers file: so I decided to simple add User to the admin group: usermod -a -G admin user

Then I used visudo to check if admin users had been set to receive sudo privileges. I uncommented the line admin ALL=(ALL) ALL. And viola!

Nothing happened. I've even tried to add user directly into the sudoers file as user ALL=(ALL:ALL) ALL, but that failed too.

Ideas?

Defaults env_reset
root ALL=(ALL:ALL) ALL
admin ALL=(ALL) ALL
%sudo ALL=(ALL:ALL) ALL

Can you post the relevant sections of your sudoers file?

Re-posted from the comment below:

[edit]admin should be %admin - Percent signs are used for groups, you could have also just added the user to be in the sudo group [/edit]

One quick thing to try is to run grpconv from a root terminal, be it by

su -c'grpconv'

from a non-root terminal

or actually loggin in as root and entering

grpconv
