I'm currently trying to find out why a recent copy of a cygwin mirror
causes the "Download Incomplete.  Try again?" error in setup.exe.  The
md5 checksums on each file within the download is good (we check them
against the md5.sum file in each package directory).  But still we get
the above error.

Is there a way to test if a downloaded cygwin will cause the "Download
Incomplete.  Try again?" error, except by running setup.exe?

By looking through the mailing list archives, I got the impression that
this happened when the setup.ini file got out of sync with the
collection of packages - but Christopher explained that setup.ini only
gets updated occasionally.

And I can confirm that: many of the package versions in setup.ini don't
match the versions of the packages present, even in stable and
installable cygwin mirrors.

Is that because setup.ini gets updated manually?  Would you like me to
try to design an easy system to regenerate it automatically when
packages are updated?  (I'm imagining a tree of per-package description
parts which change infrequently, and a script which adds the file size
and md5 sig automatically.  Perhaps it should even be a Makefile.)

I'm thinking of this email from the Cygwin-xfree list:

But is that the cause of the problem?  If not, does anyone know what
the real problem is?

If the only way is by running setup.exe, is that unlikely to damage an
older, working Cygwin install?
