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.

This question came from our site for professional and enthusiast programmers.

What happens when you run apt-get update and apt-get upgrade instead of synaptic? – Joakim Nohlgård Nov 9 '12 at 9:01
my suggestion - to use aptitude, also, aptitude install debian-keyring and this question for serverfault or superuser – zb' Nov 9 '12 at 9:04
@JoakimGebart, I get a string of errors. Pretty much the same symptoms. I could record some of those errors and post here, if you think it would help. It mainly has to do with the server connection being unauthenticated. – Fred Daniel Kline Nov 9 '12 at 13:37
You should post a snippet of the exact errors. – jordanm Nov 9 '12 at 21:59
Lenny is so far out of date that you may as well upgrade it anyway. – Michael Hampton Nov 9 '12 at 23:55

Lenny is so far out of date that you may as well upgrade it anyway. It was released February 14th, 2009. In Linux years that's almost an antique. (And Debian only promises support for three years anyway.)
