When running a fresh install, I hit this:
ERROR: Capture process failed:
Unknown errorqt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
This was due to pkexec not saving the DISPLAY environment variable. To solve
this, pass that variable as one of the environment variables to pkexec.
