You mean working for free and for Falcon? No, thank you.
Apart from this is it too early to say how stable this will all be. If we’re lucky then Steam / Proton may be the way forward. But right now is it still a few too many steps that users need to make before it works. Distros will need to pick up the new Steam as well as the more recent graphics drivers. It may work well for some of us, but others are bound to have issues and they won’t be so lucky. It’s still experimental.
Anyhow, back to Steam… The latest Steam is causing a bit of trouble. If anyone runs into it then here is what you can do to fix it.
Issue: The client won’t update the launcher properly, giving an error message regarding some failed or missing server certificate. Steam will also try to ask for an email address and wants to add a Steam account to the EVE launcher now.
My guess is this new issue is part of the progress, which Steam is making with Proton and the game.
Fix: Uninstall the game through Steam, and reinstall it again. Apply the work-around of setting Proton / WINE into “Windows XP”-mode (see steps 8-11 here).
When Proton has received a new update then make sure that you don’t have any processes of the old version left running. Check for the typical suspects such as “explorer.exe”, “winedevices.exe”, but also “eve.exe” and “execfile.exe” and terminate these should they still linger around. (A logout or a reboot will get rid of these, too.)
Result: The EVE Launcher will now start again, and show a new, first account by the name “Steam::12345678” (the number is random). One can add existing accounts again and start them as usual.
