Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I have freshly isntalled ubuntu and installed some custom drivers for my usb modem to surf the net. Problem is everything works perfectly in ubuntu 10.10 but in 11.10 what happens is that I can surf the net with firefox but when i open software centre, i dont see any option to install any application... the place where install usually is has a greyed out button names "use the source" instead.....

this is so frustrating!.... doing stuff from my terminal works though..

any ideas?

Can you run sudo apt-get update and sudo apt-get install name-of-application, for example, sudo apt-get install rtorrent and paste the output that you receive by editing your question? –  nitstorm Feb 23 '12 at 20:09
Can you post your repositories. See . You can also try an alternate mirror - (see the above link). –  bodhi.zazen Feb 23 '12 at 21:45

It sounds as if your internet connection is working as you can use firefox. My guess would be either that you need to enable your repositories or try another mirror.

Look in the "Ubuntu Software" tab and check ;)


Sometime a mirror may be unavailable for any number of reasons, try an alternate (select one close to you geographically):

mirror 1

mirror 2
