I am installing FLIRC on kodibuntu. In a terminal, I added FLIRC sources to /etc/apt/sources.list. I added "deb http://apt.flirc.tv/arch/i386 binary/" after applying sudo apt-get update, I got the following response - "W:GPG error: http://apt.flirc.tv binary/ Release: the following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3F0B7E963CBA18E3
I went to ubuntu.
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3F0B7E963CBA18E3
I got the following response: "gpgkeys: key 3F0B7E963CBA18E3 not found on keyserver"
How can I get a gpg key update for the I386 binary file?
