Hi! I think this Issue could be closed.
This fix is for a package that is not included on golang build (package crypto/ssh).

⬢[e@toolbox crypto]$ pwd
/var/home/e/wrk/goroot/src/vendor/golang.org/x/crypto

You are 100% right.

Go doesn't use x/crypto/ssh:

https://github.com/golang/go/tree/release-branch.go1.18/src/vendor/golang.org/x/crypto

I'll close this.
Thanks!
