I lost all my privilages [Kubuntu] [usermod]

I was using the usermod to add a group to myself. according to

http://www.ahinc.com/linux101/users....xisting%20user

Quote:

usermod - Modifying existing user

Options:

* -d home directory
* -s starting program (shell)
* -p password
* -g (primary group assigned to the users)
* -G (Other groups the user belongs to)

Example: To add the group 'others' to the user roger
usermod -Gothers roger

Yes I tryed that

sudo usermod -Gwww-data myuser

and now the only group I'm in is www-data. I can't even sudo it back to normal.

Is there anything I may do? root is disabled.

Thank you!

You can boot into single user mode...or you can sudo to su (this has worked for me at times):

Code:

sudo su -

it will prompt you for your users password.

I tryed sudo su however that didn't work. What I did is just insert the ubuntu CD and boot from CD. Go into the file system on the hardrive and open

sudo vim /etc/group

then just add myself to the proper groups. Restart and groups are back to normal yay :).

the format of the groups is as follows

group_name:x:group_number:user1,user2 ....
here is an example
www:x:1003:pika,flap
where pika and flap are supposdably real names and part of the group www. I don't know whats with the x its just there.

and that website above should be updated. since the users are not added but set.
