How to fix GPG error NO_PUBKEY?

Sometimes, when you upgrade the system, an error may occur GPG, which means that the key of some of the repository has changed or something happened to him. In this short article I will show how to quickly solve et this problem.



Sorry for the spelling and phonetic errors in the text.
Owner and main writer of MintGuide.org is not a native English speaker.


So, once you run the command to update the indexes of the packages in the repository, we have known the command:

sudo apt update

And you see an error GPG:

W: GPG error: http://ppa.launchpad.net trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D35164147CA69FC4

Fix this misunderstanding

Method –1

Look at the value NO_PUBKEY, in my example this value D35164147CA69FC4 and insert this value into the command to make it as I have:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D35164147CA69FC4

Method –2

Open a terminal and run the following single command:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com `sudo apt update 2>&1 | grep -o '[0-9A-Z]\{16\}$' | xargs`

This command (in theory) will automatically find and add missing security keys to the connected repository.

Method –3

Try to use a powerful utility for working with repository Y PPA Manager

Good Luck!!!
