Debian Sarge 3.1:problem sa instalacijom kernel-source-2.4.7

Pozdrav!
Da bi instalirao 'nvidia' drajvere trebam da instaliram 'kernel-source'.
Koristim 'synaptic' koji daje izlaz:

E: Invalid archive signature
E: Prior errors apply
to/cdrom/pool/main/kernel-source-2.4.27/kernel-source-2.4.27-2.4.27_2.4.27_all.deb

dpkg-deb: `/cdrom/pool/main/k/kernel-source-2.4.27/kernel-source-2.4.27-5.all.deb` is not a debian format archive

dpkg: error processing /cdrom/pool/main/k/kernel-source-2.4.27/kernel-source-2.4.27_2.4.27-5_all.deb (--unpack)

subprocess dpkg-deb --control returned error exit status 2

Failed to apply all changes!

Pre 5-6 meseci nisam imao ovaj problem...molim za savet i unapred hvala.

Probaj apt-get update
i onda apt-get install kernel-source...
Ako ni to ne radi, idi na www.kernel.org i skini source koji ti treba.
Ova greska je verovatno zato sto apt od nedavno ima novi sistem potpisa
koji bi trebalo da je mnogo sigurniji. I naravno imaju pomalih poteskoca.
Uskoro bi to trebalo da se sredi.
