Download:

	$ curl -OJR https://cygwin.com/setup-x86_64.exe
OR
	$ wget -N https://cygwin.com/setup-x86_64.exe

If using unattended (--quiet) mode, you have to specify everything else:

	$ ./setup-x86_64 -gq -R "$rootdir" -l "$pkgdir" -s $site

otherwise try semi-attended (--package-manager) chooser-only mode:

	$ ./setup-x86_64 -gM -R "$rootdir" -l "$pkgdir" -s $site

which lets you see the prompt screens and decide whether you need to change
anything.

Defaults should have been saved in /etc/setup/setup.rc and packages in
/etc/setup/installed.db the first time you installed Cygwin, so that subsequent
upgrades will use the same locations.

If your alternative package manager is not following these conventions, please
consider whether that is a safe approach if other apps are needed for upgrades,
unless your package manager uses workarounds so they are not needed.
