This should solve your problem:

$ sudo -i
 # apt-get clean
 # cd /var/lib/apt
 # mv lists lists.old
 # mkdir -p lists/partial
 # apt-get clean
 # apt-get update

Tried it but still get errors.

Though the errors reduced some, but these wont go.

Do this:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2693D732CA213C67

then:

sudo apt-get update

Post here if it didn't work.
