[HOW-TO ] retrOSMCmk2: a RetroPie installer on the Vero4K

Hi,

I’ve just moved from a Pi3 to a Pi4. Tried to redo my setup. I got past the public key issue. But there seems to be an issue with AGS in Optional Emulators. So if you hit install all, it gets to AGS then they all fail.

RetroPie-Setup version: 4.7.19 (04a74980)
System: rpi4 (aarch64) - Debian GNU/Linux 10 (buster) - Linux osmc 5.10.32-1-osmc #1 SMP PREEMPT Wed Apr 28 05:45:57 UTC 2021 aarch64 GNU/Linux

I don’t know if this is an upstream thing or a conflict with OSMC but thought I would drop it in here in case anyone knows a fix.
