I upgraded by the command:
sudo apt-get upgrade
After the update finished, the result is the same; the next time I run the command, the same result appears, something like:
Ign http://security.ubuntu.com trusty-security InRelease . . . Ign http://in.archive.ubuntu.com trusty-proposed/universe Translation-en_IN Fetched 217 kB in 1min 21s (2,648 B/s) Reading package lists... Done
I searched for a solution, but it seems I am the only one with this problem. If this question is a duplicate, could someone give me a link to the original question?
