Do you mean xubutu 14.04?

The update problem may just be a temporary issue with a repository.
If not then open a terminal and run
sudo apt-get update
to check for updates.  That should give you more information.
Probably one of the repositories is not accessible.  If you try the
same on the other machine you should be able to see what is different.
If the update runs ok then
sudo apt-get dist-upgrade
to actually fetch and install the updates.
