Can't verify a digital signature - Winetricks

Tried following this tutorial (https: //linuxconfig. org/ how-to-install-battle-net-on-ubuntu-20-04-linux-desktop) to install Battle/net on Ubuntu 20.04, but I got this error. Any ideas?

I am afraid that Blizzard does not support Linux.

It may be possible other players see this and reach out. However, you may be best off posting on a Linux forum.

Blizz does not support Linux but they also don’t stop you if you can make it work.
