"Error: failed to write, posix_fallocate failed: ENOTSUP (Operation not supported on transport endpoint)" when installing APK on Android-x86

So, I've been wanting to play PUBG for a while now, but my PC is pretty awful, then Mobile came out, and TGB didn't work properly. I've been trying out several different Android OS, but all of them need a processor that supports SSE4.2+. So, I checked out this Android-x86 OS, the 32-bit version (the first one that booted, I'm pretty sure that the game wouldn't really work anyway since the version is 32 bits, but I wanted to give it a shot anyway), and well, I can't download anything from the Play Store or install any APK. I figured out a way to install APK from the terminal, and there I discovered the error below. Why can't I install any apps on Android x86?
