The first line of your sources list is wrong. You need to make the line ineffective.

In a Terminal input: gksudo gedit /etc/apt/sources.list

Put a # at the beginning of the first line.

Save gedit. Exit gedit. Try again

Advice that arochester give you is good but if you want to correct your source list type in terminal

cat /etc/apt/sources.list

and post output here so we can correct it.This is optional because with arochester tip you will be fine.

After doing the the following, "gksudo gedit /etc/apt/sources.list

Put a # at the beginning of the first line.

Save gedit. Exit gedit. Try again"

I received the following error

E: Type 'sudo' is not known on line 51 in source list /etc/apt/sources.list

To correct it, I deleted the last lines which read,
sudo apt-key add -
sudo apt-get update

Everything works fine now. thx goes to arochester and zvacet
