 Looking back at your older posts it seems your
 proxy requires a
 password.  I have no idea
 how the configuration script sets up things
 for you, but apparently it bypasses the
 registry settings that it would
 normally
 use.

 Setup.exe supposedly should
 ask for that information via a dialog box
 when the proxy indicates it needs it, but it
 seems that your proxy just
 doesn't
 return the required 407 response header.  If you could
 figure
 out (via wget most likely) what the
 communication with your proxy looks
 like
 (with and without password) that might lead to somewhere.


I finally observed wget fail because of authentication, then work when given user, password. 
Screen output is below.
Subsequent wgets work without giving password, so there is some caching of authentication, 
apparently, at least for wget (and apt-cyg).
Setup is not as lucky, is unable to get setup.ini, and never asks for user, password.
It also only lists the download site I last used.

You can change the web site using apt-cyg mirror <uri> 
or edit /etc/setup/setup.rc /last-mirror/+1 directly.

curl -v sometimes shows when server status codes are returned instead 
of web pages, allowing you to add options to proceed further, step by 
step.
wget -d can also provide more useful information.
Packet analyzers like wireshark etc. can let you see what programs 
like setup are doing (wrong), when compared to wget working correctly.

It's quite clear that setup and your proxy miscommunicate about the
authentication.

Again, the proxy is supposed to reply with a 407 error when it requires
to authenticate the request source.  It obviously errors out, but it
does not appear to actually request authentication.  If it would do
that, then setup would ask for the user/password combination.

The proxy gives the 407 error, based on some testing
with wget -d. Even without providing user/password, it works 
around half the time, for wget. Below are some debug output from setup,
and debug output from wget testing, which shows the 407 error.

It took some time to get to it, but I've tested setup.exe using an NTLM authenticating
proxy @work today and it does exactly what it is supposed to do (pop up
a dialog box asking for the user name and password, then authenticate to
the proxy and use it for the rest of the session).

So your problem still seems to be some misconfiguration on the proxy
side that causes communication with setup.exe to fail.

Err… could it be that your proxy isn't actually of functioning as an FTP
proxy?  How about using a HTTP mirror instead?

You can call it "misconfiguration." I can call it 
"different" configuration than setup assumes.
The point remains: other programs, like wget,
 consistently work OK, without popups, when given
proxy username and password in either .bashrc
or .wgetrc, and I am sure they were not customized
for this proxy. 

Maybe a comparison of how wget handles 
authentication versus how setup handles it
could help?

 proxy?  How about using a HTTP mirror
 instead?
 
= = =

No. Wget works OK with either type. HTTP mirror
has been tried with setup, and also does not work.

From previous post, setup fails to retrieve mirrors.lst,
with an HTTP, before failing to retrieve setup.ini. 
Again, wget can retrieve these consistently OK
when given username and password.

The problem is on your side and I cannot reproduce it.  So that analysis
(which I've asked for earlier) either comes from you or you'll have to
wait until someone else can reproduce it.  In any case, I've verified
that setup.exe does ask for the user/password if it gets the required
407 error response from a proxy requiring authentication and then
correctly uses that proxy for the remainder of the session.

The output from testing with wget and setup verbose is here:

https://cygwin.com/ml/cygwin/2016-12/msg00034.html

After skimming wget and setup sources, my guess is 
it has something to do with "basic" versus NTLM 
authentication. I saw enough to know setup source is 
not nearly as thoroughly commented as wget, and
both are too complicated for me. :D 

Is there any chance of getting similar outputs from
behind your proxy, to look for differences with mine?

Thanks

Maybe your proxy is not properly handling unexpected User Agent or other 
header strings from wget and setup. 
Have you tried curl - curl often outputs only the HTTP message, and you 
can then add options to generate the correct responses or handling. 
Both curl and wget each support some user specified header addition and 
modification options.

Note that setup seems to require and support only Basic authentication 
and does not process any negotiation, so if your proxy can or does not 
fall back to support Basic authentication, only NTLM, you're hooped!

Have you tried using apt-cyg or another alternate installer?
I could suggest 
    https://github.com/BrianInglis/apt-cyg/raw/wget-non-verbose/apt-cyg
;^> 
as it has been patched to handle installing dependencies and postinstall 
scripts but does not (yet?) handle upgrades except by manually removing 
and (re-)installing packages.

You may have to do your setup and package downloads via apt-cyg, wget, 
or IE to your packages directories and use setup to do installs from 
there.

 Maybe your proxy is
 not properly handling unexpected User Agent or other 
 header strings from wget and setup. 
 Have you tried curl - curl often outputs only
 the HTTP message, and you 
 can then add
 options to generate the correct responses or handling. 
 Both curl and wget each support some user
 specified header addition and 
 modification
 options.
 
 Note that setup
 seems to require and support only Basic authentication 
 and does not process any negotiation, so if
 your proxy can or does not 
 fall back to
 support Basic authentication, only NTLM, you're
 hooped!
 
 Have you tried
 using apt-cyg or another alternate installer?
 I could suggest 
     https://github.com/BrianInglis/apt-cyg/raw/wget-non-verbose/apt-cyg

 as it has been patched
 to handle installing dependencies and postinstall 
 scripts but does not (yet?) handle upgrades
 except by manually removing 
 and
 (re-)installing packages.
 
 You may have to do your setup and package
 downloads via apt-cyg, wget, 
 or IE to your
 packages directories and use setup to do installs from 
 there.

At one time the proxy did seem to have user-agent requirements,
but lately it seems more forgiving, for wget and curl.

Thanks for your earlier curl and wget suggestions too. The output with
debug/verbose options is "interesting."

Yes, I've used apt-cyg downloads and offline setup/upgrade since about
last February. I'm using the latest version, with a small modification to
try to get "test" versions more reliably.

Oddly, trying to compare the outputs from different curl requests, with 
tkdiff, revealed that this script is no longer working for me. It worked
maybe 2 weeks ago. :/  It's always something.
