I've been trying to install FAF for some time now. The Java Launcher starts fine, but it can't join or create a game. Here is the log: https://pastebin.com/q4UtK77U.
It seems that the problem is around this:
Error opening zip file or JAR manifest missing : lib/webview-patch.jar
Error occurred during initialization of VM
agent library failed to init: instrument
I've verified that lib/webview-patch.jar is indeed in the right place.
$ ls lib/webview-patch.jar
Now I've gotten stuck, as I'm not quite sure what caused this or how to fix it, I've not been able to find a solution online.
Using Java openjdk 11, followed the instructions at https://wiki.faforever.com/index.php?title=Setting_Up_FAF_Linux, using native steam and manually installed the client.
Any ideas? Thanks in advance.
