This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Seems like that you have added some extra repositories that no longer exit.

Remove this repositories:

sudo vim /etc/apt/sources.list

Look for all lines containing a url to and comment them out by adding a '#' infront of the line.

Then try again.

Edit if you do not like vim and want to use you can use any other editor, maybe you'd like kedit for example:

sudo kedit /etc/apt/sources.list

procede to eliminate these ppa's :

  1. nvidia-vdpau doens't exist in oneric.
sudo ppa-purge ppa:nvidia-vdpau/ppa
  1. sevenmachine doens't exist in oneric.
sudo ppa-purge ppa:sevenmachines/flash

. What are PPAs and how do I use them?

(see Removing a PPA with ppa-purge)...

You should simply remove that ppa packages that do not fetch anymore.
