This is an issue that plagues me constantly. For each PPA you add to Ubuntu, you also need to import a GPG key for it. This is all fine and well – until don’t have the key and are unsure how to get it (often happens after a reformat). Try doing an update without a valid key and you’ll get the following:

BSOD - Ubuntu Updates style
BSOD – Ubuntu Updates style
W: GPG error: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY

Well we finally have a solution: launchpad-getkeys! This handy little tool will automatically determine which PPA’s require GPG keys and import them for you.

Finally. Sweet relief!

Install with:

sudo apt-add-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install launchpad-getkeys

Run with:

sudo launchpad-getkeys
