the command I gave was

what I have to do? (I'm under kubuntu 11.10)

Answer 1

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 ppa.launchpad.net 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

Answer 2

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)...

Answer 3

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