i started with ubuntu just about 3-4 hours ago. I did only install it for some software-developement purposes (ruby, phyton, perl, etc.).
When i'm going to get any kind of applications over the ubuntu software center, i'm not able to install everything. The "Install"-item in the topmenu is always locked..i only receive the following sentence, when i'm going to get more information about a application:
'available from the "main" source' - Use This Source
Nothing happens after clicking on 'Use This Source'.
If u need any further information, please tell me.
Thanks in advance, Maxi
