No matter what language I try to install support for (using System-->
Administration --> Language Support) I get the same message:

----------------------
Could not install the full language support

Usually this is related to an error in your software archive or
software manager. Check your software preferences in the Menu
"Administration".

This is when I'm connected to the net, as evidenced by the
fact that I'm sending this now.

But in Software Preferences checked I have: downloadable from the net
I have Cannonical-supported, Community-maintained, Proprietary Drivers
and Restricted by Copyright. Only Source Code is not checked. Under
Third-Party I have Hardy Heron i386 binary checked. Updates are OK.

Anybody know what might be the problem?
