Have you tried putting sudo in front of your commands? Like this:

sudo apt-get update
sudo apt-get upgrade

This is necessary for every apt command, except for apt-cache.

The sudo command will temporarily set your rights to that of root user, which is necessary for certain programs.

yup this is the mistake – Karthik T Nov 05 '12 at 07:32
Also cd apt-get update doesn't make sense, unless you have a directory named apt-get in your current directory. – green Nov 05 '12 at 10:26
