for the millionth time guys this isn't a duplicate question and if it is, them all the solutions don't work for me. i have seen this issue in a newly installed system. I tried all the things provided on the internet including creating a new sources.list, deleted the entries of list.d folder, but when I try to run the apt-get update command I get the following:

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)

here is the sources.list

deb http://archive.ubuntu.com/ubuntu trusty main universe restricted    multiverse
deb-src http://archive.ubuntu.com/ubuntu trusty universe main multiverse restricted

deb http://security.ubuntu.com/ubuntu/ trusty-security universe main multiverse restricted
deb http://archive.ubuntu.com/ubuntu trusty-updates universe main multiverse restricted
deb http://archive.ubuntu.com/ubuntu trusty-backports universe main multiverse restricted

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release

as the warning suggests its unable to fetch that url. Its your network issue. Not a source.list issue. Check if you have a working internet connection. Are you on a network that needs you to set proxy manually ? In such cases sudo apt-get update fails if proxy is not set properly for the sudo environment.

Have you tried this

   alther the sources.list file whit gedit

and then type this in the bottom

   deb http://archive.ubuntu.com/ubuntu/dists/trusty/Release
   # deb-src http://archive.ubuntu.com/dists/trusty/Release

and it might work fine this way.

Use this

http://us.archive.ubuntu.com/ubuntu/dists/trusty/Release

Instead of this

http://archive.ubuntu.com/ubuntu/dists/trusty/Release

or Change DNS to google DNS or Open DNS

Goolge DNS

8.8.8.8

8.8.4.4

Openn DNS

208.67.222.222

208.67.220.220
