I am using Ubuntu 14.04 64-bit version
Whenever I try to download some software from ubuntu Software Center
it used to show “Failed to download package files” error?
So I followed this post https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure
And tried all steps but after following step 5 of this post my software manager is not even allowing me to download rest softwares as well, install button is not coming in front of softwares in software center>
Please help me to get out this problem.
Result in terminal:
shikhar@Shikhar-asus:~$ sudo apt-get update
