You know, it is a 1000 times easier to just do $ sa-update --nogpg than to try to figure our the right way from the messages that surround "channel: GPG validation failed, channel failed", or the sa-update man page, or writing this group and asking what to do. So there, the result is gpg is defeated.
The cure is to have the error message to say "Do sa-update --import bbblllaaa", with the exact name it wants. I challenge you to figure it out just from the failure message to sa-update -D. One ends up lost reading http://www.gnupg.org/faq/subkey-cross-certify.html. It is 1000 times easier to just do $ sa-update --nogpg.
