Could not refresh the list of updates error in Update Manager

sammanadh · 05-19-2019, 08:52 AM

Hello. I'm new to linux mint. I needed to use some windows apps in my system. So I downloaded wine through the terminal by using some codes I found online. Ever since that point Update manager in my system keeps on showing this error

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 ................,
The repository 'https://dl.winehq.org/wine-bulinds/ubantu bionic InResease' is not signed.

ANY SOLUTIONS??

Hi sammanadh, and welcome to LQ.

The official Wine installation instructions are here (follow the ones for Ubuntu Bionic if you're using Mint 19.x): https://wiki.winehq.org/Ubuntu

It's always better to follow instructions on the developer's site than "using some codes I found online".

The page lists the stage where you download and add the repository key, which I think is the step you are missing:

Code:

wget -nc https://dl.winehq.org/wine-builds/winehq.key

sudo apt-key add winehq.key
