[justincm]

After downloading ubuntu_22_04.tar.gz and steamcmd_linux.tar.gz. then using copy to load them into the image

the steam user has permission denied on unzipping and un taring the archives

tar: ./Ubuntu_22_04/usr/lib/i386-linux-gnu/libLLVM-13.so.1: Cannot open: No such file or directory
tar: ./Ubuntu_22_04: Cannot mkdir: Permission denied

as root user

Build completes, but run command fails
