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:

  • Can you run the software-center from the command line and tell us of any output?. – Javier Rivera Dec 27 '11 at 08:19
  • @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 09:39
  • @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

    This question should instead be filed as a bug report, and [as such](http://meta.askubuntu.com/questions/1317/what-to-do-with-questions-that-describe-known-bugs/) is off-topic, thanks!

I've also had csome problems. Re-installing software center can't fix it.

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

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

  • Running the Software Center using 'Alt+F2' and typing `gksu software-center` to run the software center and the above solution worked for me. [(source)](https://ubuntuforums.org/showthread.php?t=1340014&page=2) – Mayeenul Islam Sep 02 '16 at 06:24
