Commands inside Waydroid shell outputs inaccessible or not found
On Arch based distributions there's a "bug" that may appear while working with lxc-attach that may cause this issue with commands inside waydroid shell like adbd or settings. A possible workaround for this would be replace the # waydroid shell command with # lxc-attach -P /var/lib/waydroid/lxc/ -n waydroid --clear-env.
