For some unknown reasons Install button is disabled in Software Center and therefore I am unable to install any software from Software Center. But it is possible to install software using command apt-get install package_name.

I have Internet connection through 3G modem but I think Software Center doesn't have internet because it shows a notification saying 'No network connection' (Sin conexión de red).

In the screenshot below you can see the problem I have described:

EDIT 1

When I run it from terminal with software-center command it outputs following messages:

2011-12-28 22:31:30,618 - softwarecenter.ui.gtk3.em - INFO - EM's: 17 15 21

Can you run the software-center from the command line and tell us of any output?. – Javier Rivera Dec 27 '11 at 8:19
@JavierRivera. Thnx for trying to help me. I have added what you had asked in the question part under "EDIT 1" section. Anything else pls let me know. – Bakhtiyor Dec 28 '11 at 17:36
Sorry, I can find nothing useful on that output. – Javier Rivera Dec 29 '11 at 9:39
@Bakhtiyor - please can you post the contents of /etc/hosts and /etc/hostname ? – fossfreedom♦ Dec 29 '11 at 13:07
are you using any proxy server(ex squid)? See on network proxy settings. – shantanu Dec 29 '11 at 13:15

I also have some problem. Re-installing software center can't fix it too. I though it's some bug.

You have an alternate solution. Just look at the top left of this picture http://i.stack.imgur.com/YrBy5.png and you will get it.

You can't click install button because it seems inactive/disable, so just go to the top left and find file -> install. Hope this will help you.
