What is the easiest and safest way of installing Wine on Linux Mint 19.x?
The answer can be found on the Linux Mint 19.x Release Notes webpages. They all recommend following this procedure:
It is really as simple as that. Using the wine-installer will give you Wine 4.0 from the Linux Mint software repositories.Release Notes for Linux Mint 19.x - Section 'Wine 4.0' wrote: Wine 4.0
To install the stable version of WINE from WineHQ, open a terminal and type:
apt install --install-recommends wine-installer
Among other things, this will install wine-desktop-files, which adds menu entries for regedit, your C:\ drive and other items which are missing from upstream WINE.
This will work on all Mint 19.x releases, from 19 to 19.3, no matter whether your desktop environment is Cinnamon, Mate or xfce.
After you have installed Wine 4.0 by executing the commandline given above, you should launch "Configure Wine" from the Mint application menu - Submenu "Wine" and configure Wine.
When "Configure Wine" is launched for the very first time, it will suggest to download and install a few more Wine related software packages.
In case you are not sure whether to agree or to disagree, agree and permit Wine to install the suggested software packages.
Once you have finished this step as well, you are ready to install Windows applications through Wine.
Please, be aware that not all Windows applications will work perfectly, when invoked by Wine. Before installing a Windows application under Wine, you may like to check the WineHQ Application Database, WineHQ AppDB, in order to find out how Wine users rate a specific application when run under Wine. Applications rated Platinum or Gold should work almost perfectly. Any lower rating promises serious trouble.
