Newer Ryzom Installer versions supposed to download client files from https://download.ryzom.com/
You can download them there as well as latest Ryzom Installer.
At the risk of sounding critical, why is it so hard for Ryzom to produce a Linux client that works without needing to go and download extra files? It's not like this is a new problem.
This thread should have been archived years ago.
From a commercial perspective:
1) how many hours have been spent on support helping players install a linux client?
2) how many players have tried to install the game, and given up and gone to play something else?
Surely, the cost of the hours needed to package the client properly is far less than the number of wasted support hours and lost subscriptions ...
Everone has an opinion, and of course are entitled to have one, but others are equally entitled to decide whether they choose to agree or disagree. Acting like a complete Muppet isn't likely going to change minds or win support :)
