I recently installed Ubuntu 14.04.1 LTS in my laptop. I am new to this OS, I previously used windows 8.1, so I don’t know much. I am having problem with updating. I cannot install and update softwares from software update. So please help me. I have also tried to update through terminal using,

sudo apt-get update

But it says.....

Err http://extras.ubuntu.com trusty InRelease                                  
Err http://extras.ubuntu.com trusty Release.gpg                                
Unable to connect to extras.ubuntu.com:http:

I want some suggestions.

  • Can we assume your sure your internet connection is working? You can surf the web? I would check to see if your network drivers are all functioning properly. But, I'm a n00b, too. I've encountered problems with network drivers, or lack thereof, clustering installs.

You may want to try,

sudo apt-get dist-upgrade

and see what happens. It can be a quick fix sometimes.
