Answer 1

i found a solution to this problem:

first, go to https://cygwin.com/mirrors.html , look for your location and click onto the FTP link.

Then, you should see 4 folders:

noarch, unsupported, x86, x86_64

click on "go back" or something like this (go back 1 folder). Then you should see a many folders. Search the"cygwin" folder and simply drag it to your desktop. Now you should have a shortcut to this FTP Folder. Now, right-click the shortcut and click onto "properties" and copy the URL.

Now, you can open the installation program. Click on "Install from Internet", All Users / Just Me (your choice), Use System Proxy Settings. Now you will get an error message (if you already got that error, it wont show up again). Ignore the error and it will ask you for "available Download Sites". Paste the URL from the shortcut into the "User URL" and click on "add". Then, a "Select Package" Window will show up. click on "all" and then on "next".

Finished!

(Im using firefox and windows 7 32bit VM VB)

Now some guys will ask: Why didnt you just put the ftp link directly into the setup?

Well, i tried that and setup crashed on me every single time. With the shortcut it worked fine.

I hope this will help. (my english skills are trash, i know)

I had the same issue. Disabling kaspersky solved it. There are a list of programs known to interfere with cygwin functionality. Please find the list here here(4.44)

Answer 3

The solution for me was enabling TLS 1.2 support in Internet Properties. But hold on! You'd better update your Windows before, because there is an update that enables support for this protocol by default. If you don't want to update your Windows, for reasons, follow these steps:

1. Go to Internet Properties, you can find this in start menu, in control panel, or hit Win + R and run: Inetcpl.cpl.
2. Go to "Advanced" tab.
3. Scroll to "Security" section.
4. Check Use TLS 1.2 option.

Run Cygwin installer again and now it should work. If not, maybe try with other security options.

How did I find out this

After a few failed install attempts, I decided to look for some hints in Event Viewer, and to my surprise, I found them. In System logs I spot lots of errors from Schannel service with a meaningless description:

The following fatal alert was received: 70.

I Googled for further explanations. Errors like these are caused by SSL failures, so something wrong was happening between Cygwin installer and Cygwin site. Something in my head told me to check Internet Properties for options relating to security, so I did and I found disabled protocols.

Answer 4

I do not have admin privileges on this windows 10 host, but this worked:

setup-x86_64.exe -B -O -s http://mirror.clarkson.edu/cygwin

which allowed me to install cygwin from that one mirror site.
