What are the good repositories to keep our system up to date ?

Asked by Marchombre

Hi !
Sorry for this lame question, but i'm a bit uncertain about which depositories I should use :
There is this one :
http://ppa.launchpad.net/moblin/ppa/ubuntu karmic main
It seems related to the moblin ubuntu hacker's team.

But also :
http://ppa.launchpad.net/ubuntu-moblin-remix/ppa/ubuntu karmic main (yours ?)

This depository is giving me the following error (sorry, it's in french) :
GPG error: http://ppa.launchpad.net karmic Release: Les signatures suivantes n'ont pas pu être vérifiées car la clé publique n'est pas disponible (no public key was found) : NO_PUBKEY 5A9BF3BB4E5E17B5Impossible de récupérer (he can't find what follows) http://ppa.launchpad.net/ubuntu-moblin-remix/ppa/ubuntu/dists/karmic/main/binary-i386/Packages.gz 404 Not Found
Le téléchargement de quelques fichiers d'index a échoué, ils ont été ignorés, ou les anciens ont été utilisés à la place. -(the last line tells me that the download of some files has been ignored.)

Is it normal that http://ppa.launchpad.net/ubuntu-moblin-remix/ does not exist ? Should I remove it ?
