Mutual GNU / Linux

I didn't see anyone mention the following, and I might have missed it, but did you install the 32-bit architecture?

dpkg --add-architecture i386

Just asking

Had some issues with rystart on manjaro, for some reason (I suspect that I don't have the specific python 3.8 parts installed) the installer script could not populate the game directory with the client & updater (" could not find ... ryzom_client_patcher" )

Downloading https://download.ryzom.com/client_linux64.zip  and extracting it in the right location (/home/{username}/.local/share/Ryzom/ryzom_live/) solved this for me. Hope it helps :)
