go get no working with Go modules: no matching versions for query "latest"

[ahmetb]

go-get for an existing package doesn't work off the bat.

I had to talk to someone working on client libraries to figure out the workaround (@master). This doesn't sound ideal.

That package is not part of a published module, which is why you can't go get it normally but can with @master. This seems to be WAI. Closing, but let me know if you have further questions.

Also: that package is about to be deleted (see: #382)
