With --quiet-mode noinput, Cygwin setup sits at the appropriate
dialog, but it's of course non-responsive.
Would it be possible in these situations for Cygwin to abort,
preferably with a non-zero exit code?
The background to this was running Cygwin setup in GitHub Actions (so
UI not visible), _without_ specifying --site, where the Cygwin
installation had been restored by actions/cache but not the registry
setting in HKLM\SOFTWARE\Cygwin\setup meaning that setup could not
find setup.rc and consequently determine the last-used mirror. The GUI
therefore invisibly froze at mirror selection.
That issue has obviously been fixed, but it would seem sensible that
Cygwin's setup doesn't ever display a dialog _requiring_ input where
all that input has been disabled!
Thanks for reporting this!
Oh, this is a weird one:
The '--quiet-mode' implentation is all rather ad-hoc, and so there's
been no comprehensive audit of the setup code to ensure that all the
possible places where we potentially stop for interaction are instead
handled automatically.
But, this is a deliberate choice in some ancient logic, which
deliberately drops back into attended mode, just in this one specific
place (when there are no package repository site URLs specified).
Since this seems counter-intuitive and completely unhelpful, I've
applied a change as you suggest, so we'll stop with an error instead.
