Total Crash when compiling Editor for Linux

I am attempting to compile the UE4 Editor for Linux (specifically Fedora 28). However, when I run Setup.sh, it tries to update the engine’s dependencies, reaches about 84%, and then the entire system totally locks up. I can’t switch terminals with Ctrl-Alt-F2, the clock doesn’t move, I can’t move the mouse, nothing… I’m guessing some sort of kernel panic is occurring at that point, but I can’t get to anywhere I could view a log file. What sort of process would the build be running that would crash the entire system like this, and how can I fix it?

Can you provide bit more info? Your system specifications for one? The Setup.sh is mostly git operation(apart from downloading the toolchain and other things). Also what version of UE are you trying to compile? Did the compilation just yesterday on 4.20 branch and went ok.
