key error for security repositories

[bmr5770]

I use apt-get from the command line and I get the following doing an update:

....

W: You may want to run apt-get update to correct these problems

Of course, the update doesn't fix this issue. I'm confused as to how to get the keys. I've seen one repo where someone just d/l a key then used apt to update the key file and I've seen another set of directions going to a pgp site using gpg to try to get the key.

I tried the 2nd set but I'm behind a proxy server and I *think* that's stopping me from getting the keys:

$ gpg --keyserver subkeys.pgp.net --recv KEY

What's the right way to go about this?

Thanks,

Re: key error for security repositories

no one knows? How are the keys initially set? This install started from the Beta 2 of Dapper Drake.
