The top of Wine's download web page has the following warning:
The WineHQ repository key was changed on 2018-12-19. If you downloaded and added the key before that time, you will need to download and add the new key and run sudo apt update to accept the repository changes.
On the news section of the website there's no such mention of a key change. How do I verify the site hasn't been compromised? Would I have to find it through some news outlet? It doesn't appear there's other official Wine sources of information.
