I am unable to view any screen in my ubuntu, Also, when i do apt-get update.

I get below errors :-

  1. Failed to download repository information. Check your internet connection

Details

W:Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file),
E:Some index files failed to download. They have been ignored , or old ones used instead.

How can i solve the issue.

Please try,

echo "deb http://archive.ubuntu.com/ubuntu trusty main universe restricted multiverse | sudo tee /etc/apt/sources.list
echo "deb http://archive.ubuntu.com/ubuntu trusty-updates main universe restricted multiverse" | sudo tee -a /etc/apt/sources.list"
echo "deb http://archive.ubuntu.com/ubuntu trusty-security main universe restricted multiverse"  | sudo tee -a /etc/apt/sources.list"
echo "deb http://archive.ubuntu.com/ubuntu trusty-backports main universe restricted multiverse"  | sudo tee -a /etc/apt/sources.list"
sudo apt-get update
sudo apt-get upgrade

The first lines will reset your repository. Then the update might work.

    After that, you `sources.list`, has only one entry. That's a very dangerous answer. – A.B. Jun 18 '15 at 04:44

    I think you meant to use ">>" instead of ">" which will append to the file instead of truncating it before writing each line. – Nathan Osman Jun 18 '15 at 04:47

    Test your answer and good luck. -1000 – A.B. Jun 18 '15 at 04:48

    This answer is still incorrect. Shell redirection takes place before invoking `sudo` and therefore the command will fail since the invoking shell does not have permission to write to the file. – Nathan Osman Jun 18 '15 at 04:57
  • Adding to what Nathan Osman said, your edit is wrong. Appending the first line doesn't delete what's already present, so it doesn't reset anything. I rolled your answer back to my revision. – kos Jun 18 '15 at 05:08
  • This [ http://askubuntu.com/a/467824/259823 ] ans is also doesn't helpful and probably incorrect, and after using it my pc is now unable to update/install software. I don't have down vote permission till now so unable to do it. – Soumyadip Das Feb 11 '16 at 10:04
