Is there a way to know whether am the administrator of my Ubuntu 14.04 ? If not, how can I became the administrator ?
In the default GUI, open the System Settings and go to the “User Accounts” tool. This shows your “Account Type”: “Standard” or “Administrator”.
On the command line, run the command id or groups and see whether you are in the sudo group. On Ubuntu, normally, administrators are in the sudo group.
You may have administrative access if you've been directly added to the list of sudoers — this is more likely if the administrator is familiar with Linux or Unix in general and didn't use the default Ubuntu method. Try running sudo echo ok and enter your password; if this prints ok, you're an administrator.
