Can someone help me with this fail, I get it when I run the su command.

Failed to open connection to "session" message bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Thanks

By default, the Root account password is locked in Ubuntu.

This means that you cannot login as Root directly or use the su command to become the Root user. However, since the Root account physically exists it is still possible to run programs with root-level privileges. This is where sudo comes in - it allows authorized users (normally "Administrative" users; for further information please refer to AddUsersHowto) to run certain programs as Root without having to know the root password.

See the community Ubuntu help on Sudo for more details. Also see Why is there no option to login as root? for why root is disabled in Ubuntu.

Hope this helps
