I'm trying to update an old[is] BBB debian installation.
When I do 'apt-get update' it mostly works but I'm getting the
following errors:-
Get:6 http://repos.rcn-ee.net wheezy Release [2,169 B]
Err http://repos.rcn-ee.net wheezy Release
W: A error occurred during the signature verification. The repository
is not updated and the previous index files will be used. GPG error:
http://repos.rcn-ee.net wheezy Release: The following signatures
couldn't be verified because the public key is not available: NO_PUBKEY D284E608A4C46402
W: Failed to fetch http://repos.rcn-ee.net/debian/dists/wheezy/Release
W: Some index files failed to download. They have been ignored, or old
ones used instead.
How do I get things to catch up properly?
