I found an error on right top of the screen in "red cricle" . It say:

A problem occured while checking for updates.

I am not able to open open software updater and software center.

I have added the terminal output of : sudo apt-get update. Please comment — user199639, Apr 23 '15 at 14:37
So far, no error occurs. Ok, than run sudo apt-get upgrade. And post the error if there is one. — A.B., Apr 23 '15 at 15:38
The output from sudo apt-get upgrade is updated in question. — user199639, Apr 23 '15 at 16:59
Hmmm, no errors. Run software-center in a terminal and update the question. — A.B., Apr 23 '15 at 17:01
Added the ouput of software-centre in terminal to the question. Also the edits are not getting properly indented. Please enlighten me. — user199639, Apr 23 '15 at 17:43
