When I sudo apt-get update I get the error shown below.

W: An error occurred during the signature verification. 
The repository is not updated and the previous index files will be used. 
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 76F1A20FF987672F
W: Failed to fetch https://dl.winehq.org/wine-builds/ubuntu/dists/bionic/InRelease
The following signatures couldn't be verified
 because the public key is not available: NO_PUBKEY 76F1A20FF987672F
W: Some index files failed to download. They have been ignored, or old ones used instead.

So I go ahead and change my mirror as suggested by this Ask Ubuntu answer. Then I restart the computer. And I still get the same error above when I sudo apt-get update.

Let's try and reinstall the keys.

$ wget -nc https://dl.winehq.org/wine-builds/Release.key && sudo apt-key add Release.key
File ‘Release.key’ already there; not retrieving. OK

And I might as well ping -c3 archive.ubuntu.com and my packet loss is 0%. What else do I need to do?

    It looks like the new update for wine is signed with a different key than the Release.key they are hosting... – user3074620 Dec 20 '18 at 03:20

    Please use code formatting for command output (just like commands), not quote formatting. – muru Dec 20 '18 at 05:08

As of 2018-12-19 08:07 there is a new winehq.key keyfile as mentioned here.

Download the new repository key and add it to the list of trusted keys:

cd /tmp
wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-key add winehq.key
sudo apt update

As mentioned by @jason-hunter in a comment, apt update will ask if you accept the changes in the repository, whereas apt-get update will show an error and fail.

Note that after adding the new keyfile, it is better to use apt update rather than apt-get update, as it will prompt you to accept the changes.

So in full:

wget -nc https://dl.winehq.org/wine-builds/winehq.key && sudo apt-key add winehq.key && sudo apt update

    I also added the repository sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main' and this solution worked. As mentioned you must use sudo apt update and not sudo apt-get update. apt forces you to explicitly accept, whereas apt-get does not and will yield an error. If you have other versions of Ubuntu your repository to add can be found here https://wiki.winehq.org/Ubuntu – Display name Dec 21 '18 at 13:54
  • I would consider adding rm winehq.key or saving the file to the /temp at the beginning. Thanks anyway! – kcpr Jan 03 '19 at 13:14

Inspecting https://dl.winehq.org/wine-builds/, there's a new file winehq.key. Try using that instead, as its fingerprint seems to match the error:

# curl -sL "https://dl.winehq.org/wine-builds/Release.key" | gpg --dry-run --import --verbose
gpg: pub  rsa4096/818A435C5FCBF54A 2015-11-23  Sebastian Lackner (WineHQ packages) <sebastian@fds-team.de>

This command worked for me:

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

I recently was getting the same error too:

Err:3 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 76F1A20FF987672F

As it turns out, the pubkey needed to be added to my host. Adding the key is the last 8 digits of the key you see there F987672F. So add that to the following to add the key to your host:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv F987672F

Hope this helps!
