This question already has an answer here:

I accidentally unchecked the option to install third party proprietary softwares like mp3 codec during the installation of ubuntu.
Now I want to install them again. Is there any way to installing it from the CD instead of downloading the whole restricted extras package.
I am from a remote village with only 128 kbps dialup modem.

  • Excuse me @Mitch, the post you suggested does not describe how to install the packages later from cd, without downloading from Internet. – fz_salam Jun 5 '13 at 10:10
  • Sorry, Take a look at this Post, it will show how to do that. – Mitch Jun 5 '13 at 10:15
  • I'm not sure, but I believe that when you check the option to install third part software, it downloads it from the internet, not from the CD. I'll keep looking :) – SimplySimon Jun 5 '13 at 10:21
  • Thanks @SimplySimon, for the point. Is there any way to just download mp3,mp4 and avi decoders only from the package.. without flash player and other mess? – fz_salam Jun 5 '13 at 10:43
  • I checked your post @Mitch. But it still needs broadband internet. I am sorry. But I dont have any option to download the 106 MB package :( – fz_salam Jun 5 '13 at 10:47
