Hi

I have been having this problem on multiple computers. When I do an
apt-get update I get this:


W: GPG error: http://mirrors.kernel.org testing Release: The following
signatures couldn't be verified because the public key is not available:
NO_PUBKEY 010908312D230C5F
W: GPG error: http://ftp.debian.org testing Release: The following

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