PPA for Wine and playonlinux for 20.04?

Solution 1:

I do not really find a reason to add the two below PPAs/repositories to the system.
The PlayOnLinux installed from repository allows user to download and install any (including latest) version of Wine for user-specified wine prefix (virtual C: drive). So there is no need to add system-wide Wine repository to the system IMHO.

But here they are:

• PlayOnLinux

  wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -
  sudo wget http://deb.playonlinux.com/playonlinux_cosmic.list -O /etc/apt/sources.list.d/playonlinux.list
  sudo apt-get update
  sudo apt-get install playonlinux
  

  Note: the above repository has latest PlayOnLinux 4.3.4 (last modified 24 Dec 2018) and this version is available in the official repository, so there is no practical reason to add this repository.

• WineHQ

  sudo dpkg --add-architecture i386
  wget -O - https://dl.winehq.org/wine-builds/winehq.key | sudo apt-key add -
  sudo add-apt-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ focal main'
  sudo apt install --install-recommends winehq-stable
  

  Note: here we follow official guide from WineHQ.
