I'm a complete newbie as I've just installed Xubuntu 9.04 on my PS3, and I have no experience with any open source software.
Anyways, the installation went fine - no problems. I logged in for the first time - no problem.
When i try to perform almost any task, I'm met by a box where I'm suppose to type my password. I do, and the result is:
Failed to run /usr/sbin/synaptic as user root.
The underlying authorization mechanism (sudo) does not allow you to run this program. Contact the system administrator.
I've been looking around a bit and it seems there might be problem with my sudoers file? When I in the terminal type "sudo synaptic" or any other sudo command, I type my password and the result is:
adameliaz is not in the sudoers file. This incident will be reported.
I've not edited this file - dont know how to.
Typing "groups" in the terminal:
adameliaz cdrom audio admin
Any help appreciated
