On my old 32-bit Ubuntu 10.04, I used gpg, and it worked great. It was simple to install and use.
On my new 64-bit Ubuntu 10.10, I can not figure out what to do.
I think they did away with the great gpg product, and now have something called gnugp or gnugp2.
I installet gnugp2. It seemed to install okay. But it won't work. The system keeps telling me it can't find gnupg, or gnupg2, or whatever.
