unrecognized import path "golang.org/x/crypto/ssh/terminal"

[EncoderPtd]

I'm new for GO...

When i execute go get github.com/zmap/zgrab2 it shows:

package golang.org/x/crypto/ssh/terminal: unrecognized import path "golang.org/x/crypto/ssh/terminal" (https fetch: Get https://golang.org/x/crypto/ssh/terminal?go-get=1: dial tcp 216.239.37.1:443: connect: connection refused)
package golang.org/x/sys/unix: unrecognized import path "golang.org/x/sys/unix" (https fetch: Get https://golang.org/x/sys/unix?go-get=1: dial tcp 216.239.37.1:443: connect: connection refused)
package golang.org/x/net/idna: unrecognized import path "golang.org/x/net/idna" (https fetch: Get https://golang.org/x/net/idna?go-get=1: dial tcp 216.239.37.1:443: connect: connection refused)

Is there anything wrong with the git repository path?

And then i try to execute make in ../zgrab2 it shows:

cd cmd/zgrab2 && go build && cd ../..

@EncoderPtd Is this problem unique to zgrab2, or do you get it with all libraries, e.g. go get -u -v golang.org/x/tools/cmd/goimports? If the latter case, it is almost certainly an environment problem.

In any case, my immediate thought is that this may be a problem with your GOROOT environment variable; do you actually have go installed in /home/user/Downloads/Go/go? i.e., if you run which go, does it return /home/user/Downloads/Go/go/bin/go?

@justinbastress
Thanks all the same. I find it is due to the internet problem, for some reasons i can't access golang.org/x.
So i have to download the repository form github and manually create folders x/tools, x/crypto, etc. Then move the github.com/golang/crypto, etc. to golang.org/x/crypto.
Heart tired :）

Then move the github.com/golang/crypto, etc. to golang.org/x/crypto.

@EncoderPtd Where is this golang.org/x/crypto located?
I've created it under /usr/local/go/src/HERE and /usr/local/go/HERE but still get errors!

@EncoderPtd
I fix that by go get

@Drjacky E... I meant i can't access https://golang.org , the website.
If you can access it, then just follow the official doc is ok, i think.
If you've installed go successfully, the golang.org/x/crypto folder is under GOHOME or somewhere the go get command download resources.
