I am also in that same position as Tobias'- and I suspect others as well. So - has anyone got a method for a fix yet ? I thought about pulling off debian-archive-keyring package, but that tells me I could be about to really do damage to my system, so I (i think sensibly) refrained. I did try a.... apt-get install --reinstall debian-archive-keyring But that didn't work. TIA -- AM
