Well this did not helped I did try that before you had replied.I do
not know why it did not worked.

osboxes at osboxes:~$ sudo apt-key adv --recv-keys --keyserver
keyserver.ubuntu.com 3B4FE6ACC0B21F32
Executing: /tmp/apt-key-gpghome.9t5ntBXbgT/gpg.1.sh --recv-keys
--keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32
gpg: keyserver receive failed: Connection timed out

What fixed my problems was setting the location of updates in software
center to Main server rather than
servers in US.
