If you got this error :

W: GPG error: http://ppa.launchpad.net precise Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 2EA8F35793D8809A

While updating your ubuntu or debian system.

Here’s the workaround :

gpg –keyserver pgp.mit.edu –recv-keys 2EA8F35793D8809A

gpg –armor –export 2EA8F35793D8809A | sudo apt-key add –

after that, you can

sudo apt-get update

without problem ;)

      The pubkey in this case is MY pubkey, so if you use the same pubkey as mine that’s the problem, you should use the pubkey given by the error message of your system

      Best of luck :)
