I really pulled a boneheaded maneuver and removed all of the Debian testing keyrings from my LMDE installation. Only thing I have left is one for Squeeze stable and one for Linux Mint repos. No testing, no Debian multimedia--nothing. I was running the default LMDE with sources set to testing. I have no idea how to reinstall these, Google's no use and Synaptic refuses to update without them so any help would be greatly appreciated. Please don't ask me how I managed this since I don't know myself. I should know how to fix this but my brain has deserted me. [banging head against wall] Please help?
