Ubuntu: Fixing NO_PUBKEY CC919A31E23C5FC3 error from Automatix repository

Recently, my apt-get updates started failing with:

W: GPG error: http://www.getautomatix.com edgy Release:
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY CC919A31E23C5FC3
W: You may want to run apt-get update to correct these problems

This was easily fixed with:

$ gpg --keyserver subkeys.pgp.net --recv CC919A31E23C5FC3
gpg: requesting key E23C5FC3 from hkp server subkeys.pgp.net
gpg: key E23C5FC3: public key "Arnav Ghosh (Automatix Team Lead) <greyrod {at} gmail(.)com>" imported
gpg: Total number processed: 1
gpg:               imported: 1
$ gpg --export --armor E23C5FC3 | sudo apt-key add -
OK

Now, apt knows about the gpg public key for Automatix and doesn’t complain when I do sudo apt-get update.

    That should be –export, right?

    If you mean double-hyphen export, then yes. That’s what I typed, but WordPress’s overly aggresive filters are mangling it. Ugh.

    Marc,
    Thanks a million although I still had to export the public key to a file and then go to System>Administration>Synaptic Package Manager>Setting>Repositories>Authentication>Import Key File and import it. For those who are unsure how to export to file
    $ gpg –export “NAME OF YOUR KEY” > nameofyourkeyfile

    Thanks again Marc it helped eliminate the error completely.
