I try to submit my app with the command in the title, but the build failed:
Error message: 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 *
* is my key (don't know it is safe to share it)
If i run this command:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ******
It is said my key isn't change (so don't need to add it again).
Any idea?
You need to have your public key attached to your Launchpad profile.
