GPG Error w/sudo apt-get update/upgrade

**Sidewinder1** · December 13th, 2012

Over the years I have seen this type of error message and, with time, somehow it has always just cleared itself. Frankly I'm getting tired of seeing it {for several weeks or so..}, and would like to correct it once and for all. Here is the exact message:

Code:

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

Specific, step by steps would be more than greatly appreciated.
TIA.

P.S. If it's a deficiency within openprinting.org, would launchpad be the best place to report it?

Well, took me well over a month, almost 2, to read and try the link that you so kindly provided, many thanks for that, BTW. I, like some of the other responders in those various threads, had limited success. Those commands listed did clean up many items alas, the "openprinting.org" signature/keyring issue still exists.
Perhaps I'll just have to contend with it; there don't seem to be any significant ramifications as a result of the error, yet,
Thanks again for your most valued assistance.
