Ubuntu 14.04: PPA key not found on keyserver

Running “apt-get update” ubuntu complains about missings ppa keys.

In my case I was trying to install Libre Office and the missing key was 83FBA1751378B444.

I couldn´t find any key running:

sudo apt-key adv --keyserver --recv-keys 83FBA1751378B444

The message that I gog in the console was:
gpg: requesting key 83FBA1751378B444 from hkp server
gpgkeys: key 83FBA1751378B444 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

The solution to me was running:

 sudo launchpad-getkeys 

and the I could finally run “apt-get update”.

Ubuntu 14.04 : NO_PUBKEY issue when running apt-get update

Launching sudo apt-get update you might get the NO_PUBKEY issue. Something like:

W: GPG-Fehler: trusty Release: Die folgenden Signaturen konnten nicht überprüft werden, weil ihr öffentlicher Schlüssel nicht verfügbar ist: NO_PUBKEY EFD5FA852F20733F

Well it´s very simple. Just execute the following (specifying the missing public key):

[email protected]:~$ sudo apt-key adv --recv-keys EFD5FA852F20733F

And then run sudo apt-get update again. The error will disappear.
