What did you do? What did you expect to see? What did you see instead?

Installed go and attempted to use go get to fetch a gitlab repository via git:// instead of https://

I found this URL: #6968

I added a git config for my URL.

[url "git@gitlab.<myhost>:"]
    insteadOf = https://gitlab.<myhost>/

Running go get gitlab.<myhost>/blah/blah.git returns unrecognized import path with the https url still in the https fetch (which gets a connection refused). Is insteadOf still the correct way to do this as per the linked issue?

Hi @denisemauldin,
Can you paste the output of go get -u -v gitlab.<myhost>/path/to/pkg?

What is the output of curl https://gitlab.<myhost>/path/to/pkg?go-get=1?

On gitlab.com, it returns a meta tag for the go command regardless of whether the package even exists or whether you're logged in:

$ curl https://gitlab.com/andybons/pkg?go-get=1
<html><head><meta name="go-import" content="gitlab.com/andybons/pkg git https://gitlab.com/andybons/pkg.git" /></head></html>

With the following settings in my .gitconfig, insteadOf appears to work for me when I attempt to download a private package of mine at gitlab:

[url "git@gitlab.com:"]
	insteadOf = https://gitlab.com/

This leads me to believe that git isn't broken (I'm using 2.19.1 as well) But I don't have access to a custom host, so it's difficult for me to diagnose further.

@andybons andybons added this to the Unplanned milestone Oct 26, 2018

@andybons Here's the output for your questions. Our host is internal/local and does not support https, which is why I'm trying to change git from using https:// to git://. Thanks.

@denisemauldin Thank you for following up with the output. The issue is that your server does not support SSL/TLS (https) so it can't get at the meta tags needed by the go command to even use the git:// URL. My advice would be to encourage whomever administrates the local server to enable https://.

I'm sorry that I don't have a better solution for you. More context can be found at #27254 (comment)

Closing out for now. Please comment if you feel this was in error.
