Error: Failed to build UnrealBuildTool in Manjaro (Unreal Engine 5.0.2)

For the others who posted still having issues. The two vars i posted above are in relation to this error:

The SSL connection could not be established, see inner exception

The other error i read above:

Process terminated. Couldn’t find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

is not related to OP’s issue. Don’t know about the others if it’s also related. But maiby output your error just to be sure. Also sorry for late reply. I’m not on the forum a lot.

But just as a general tip. Try to find the exact issue inside your error message and look that up. That’s actually how i found the fix I posted.
