Ubuntu – Error while trying to sudo apt-get update GPG, no sign repository

aptgnupgupdates

I didn't quite understand how to fix these stuff from other posts. Can someone help me?

W: GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 818A435C5FCBF54A
E: The repository 'https://dl.winehq.org/wine-builds/ubuntu bionic InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Best Answer

When you are getting a public key error, the key itself is the last 8 digits of the NO_PUBKEY.

To install it run the following line

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 5FCBF54A

Then rerun your

sudo apt update

Hope this helps!

It seems that you need to visit corresponding software.opensuse.org OpenSuSe site and then follow instructions from it for the Ubuntu:

You can add the repository key to apt. Keep in mind that the owner of the key may distribute updates, packages and repositories that your system will trust (more information). To add the key, run:
wget -nv https://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_16.04/Release.key -O Release.key
sudo apt-key add - < Release.key
sudo apt-get update

Also note that OpenSuse build service page for this repository is located on build.opensuse.org.
