Wine 6.0 has been released as the newest stable build. You can read about it at winehq.org. I use Wine to run a couple of MS Windows programs that I haven't found good Linux replacements for (Photoshop and Omniforms, I know GIMP is a good Photoshop replacement but I'm used to Photoshop and the workflow is not the same, besides I haven't taken the time to learn GIMP)...Anyway, let's install Wine 6.0 on Ubuntu 20.04 LTS (or 20.10 noting the difference in step 3).
Open a Terminal Window and type the following commands:
1. Enable 32-bit support on your system.
sudo dpkg --add-architecture i386
2. Add the Wine keys to your system.
wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-key add winehq.key
3. Add the repository for Ubuntu 20.04 (only run one of these commands)
IF YOU'RE RUNNING 20.04
sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ focal main'
IF YOU'RE RUNNING 20.10
sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ groovy main'
4. Install Wine 6.0
sudo apt install --install-recommends winehq-stable
If you want to check your Wine Version just type the following in a Terminal Window;
wine --version
That's it you're done.
*NOTES: When I ran Photoshop after the update, Wine asked to install a couple of items it needed to work. I just clicked on the yes button. On step 1, I had already enabled this but running the command again did not hurt anything.
