I get the following message when updating now:
W: GPG error: http://www.openprinting.org lsb3.2 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7A4B44C2D2A2203E
Is there something wrong with the repository for "www.openprinting.org". I think this has been in my software sources list for some time now and it is all of a sudden becoming a problem. Seems to not be updating because of some key problem I guess.
Any fixes or is there a new repository or something?
I'm still on Ubuntu 10.04 LTS...
