My neighbor calls me to fix things when his cats walk on his keyboard and cause problems that he can't fix. This time it happened while he was running synaptic package manager.
After the reload, when we mark the updates, everything is unauthenticated. I have never encountered this before and have no idea how to recover.
Is there a config file I can tweak to fix this?
Edit: I've added a bounty to encourage some solutions.
