Ubuntu does not use the same manner of gaining root access as most linux distros, so have a look at Ubuntu: RootSudo (https://help.ubuntu.com/community/RootSudo) which will tell you all about it.

if you are in the admin group, you can use su to gain root access. the password is your user password then.

No ,you can't! Not quite.

Try su in terminal and you'll see what I mean.

You can use sudo su, if you really must, but there is often little need for that as sudo <command> will do the same thing.

sudo su could be useful if carrying out a complex sequence of commands that take a long time, and where the default timeout of the sudo root permissions might occur, but if you're doing that kind of complex terminal work, you would probably know enough to get a proper root account enabled. For most users sudo command is sufficient.

See Root-Sudo in my signature.

I don't know how to recover a lost password if it's that thats the problem..

but try set a new.. doing the following



Click Applicatons -> Accessories. Click Terminal.
A new window appears with a prompt. Key in “sudo passwd“.
System will prompt you to enter the new root password twice. Now, you are done with your new root password.


should be helping, let me know if it dosn't

You can also reset the password using this tutorial:

jus type in terminal

sudo su

passwd

By the way, what is the difference between sudo su and sudo sh in Ubuntu?
