Hi people,
I just re-installed Linux on my machine and I am trying to update it by using the command
sudo apt-get update
and the error messages I get in the terminal are

How do I fixall these problems above mentioned ? and I also have a problem whenever I download GNOME 3. My desktop enviroment plays up when I adjust it. So, the bar where the three icons are (close window, minimise/ maximise and hide) is gone for some reasons. The desktop runs really really slow and usually, I would have to restart my laptop.
I'd appreciate your help.
cheers,
