Problem
If you boot a Fedora 39 or Fedora 40 installer for the Sugar on a Stick spin, the installer doesn’t start when you try to launch it.
Cause
PolicyKit needs to be running in order for the installer to start. For some reason, it’s not started automatically, and therefore the installer fails to start.

Workarounds
After finishing the initial wizard, click on the menu icon in the top right corner, find Terminal in the list, and click on it. Once in the Terminal, run these commands:
/usr/libexec/xfce-polkit &
liveinst
The first command starts PolicyKit (which should’ve been started automatically), the second starts the installer. If you do this, the installer should start correctly.
