apt-get dist-upgrade

Pessoal
Passei recentemente de sarge para etch, e logo na primeira vez que fui fazer o dist-upgrade deu o seguinte erro:
Need to get 0B/224MB of archives.
After unpacking 64.2MB of additional disk space will be used.
Do you want to continue? [Y/n] y

Um amigo me disse que teria que mudar o kernel(2.6.8-2-k7) para o 2.6.12-1-k7 pois os problemas com udev ja estavam solucionados. Quando tentei fazer isso, deu o seguinte erro:
 apt-get install linux-image-2.6.12-1-k7

Ou seja, nao to conseguindo fazer nenhuma coisa nem outra. Dei uma pesquisada no google, e resolvi seguir alguns passos de duas das respostas que encontrei, mas acaba dando na mesma.
Se alguem puder me ajudar, agradeco muito!
