@sapiens-sapide as @mvdan mentioned, did you check that your x/sys/unix clone wasn’t on a branch or some other detached git state? Did you get an error, e.g. like the following while doing go get -u golang.org/x/sys/unix:

# cd /Users/tklauser/go/src/golang.org/x/sys; git pull --ff-only
You are not currently on a branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

package golang.org/x/sys/unix: exit status 1

Could you check the result of running git symbolic-ref HEAD in $GOPATH/src/golang.org/x/sys? If this doesn’t return refs/heads/master make sure to git checkout master and then try go get -u golang.org/x/crypto/ssh/terminal again?

Happens to my CI as well with a fresh context, in an alpine Docker image.

It downloads all vendors from scratch everytime using glide, and yet it always gives me the same errors as the other people here:

The version of golang.org/x/crypto that it uses is the commit 2509b142fb2b797aa7587dad548f113b2c0f20ce.

I was hit by this after updating my vendor https://travis-ci.org/allegro/marathon-consul/builds/301938144#L596

Cannot reproduce on neither Darwin not Linux with GOOS=darwin.

@sapiens-sapide Could you try to go get -u golang.org/x/sys/unix and then go get -u golang.org/x/crypto/ssh/terminalagain?
