I am an ubuntu amateur trying to set up an ubuntu 11.04 server on a tower. I want to install things like ssh client/ server and gksudo on it but I get errors when trying to do so. I tried to update, but I get 404 errors. I have already tried to install fix404 but it seems there is no "app-add" command... After many hours of failure, I turn to you, wise people of the internet. You are my last hope. help?

Please note that Ubuntu Server 11.04 has already reached end of life. This means that the repositories for 11.04 are already switched off. Therefore you get the error code 404 from the repository servers.

You can either use 12.04 which is a LTS (Long Term Support) Release which is supported until April 2017.

The other possibility is to use 13.04 which is the current release and supported until January 2014.
