"go get google.golang.org/grpc" failing: unrecognized import path

So I am trying to install my Go app's dependencies on my Raspberry 3/Raspbian system with "go get" and running into the following when trying to install gRPC for Go:

[pi@raspberrypi-1 camera-service] 17:32:28 % go get google.golang.org/grpc
package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp: lookup google.golang.org on 192.168.1.1:53: read udp 192.168.1.64:33524->192.168.1.1:53: i/o timeout)

Meanwhile I am able to install other (non-google.golang.org) dependencies (for example go get github.com/asaskevich/EventBus) just fine.

To me this looks a DNS problem -- 192.168.1.1 is my router, 192.168.1.64 is my RPi. However I can resolve the address just fine:

[pi@raspberrypi-1 camera-service] 17:32:52 % host google.golang.org
google.golang.org is an alias for golang.org.
golang.org has address 216.58.209.145
golang.org has IPv6 address 2a00:1450:400f:804::2011
golang.org mail is handled by 1 aspmx.l.google.com.
golang.org mail is handled by 2 alt2.aspmx.l.google.com.
golang.org mail is handled by 2 alt1.aspmx.l.google.com.
golang.org mail is handled by 2 alt3.aspmx.l.google.com.

This is weird. Also I have installed the same packages on another system np.

My environment is

- Go 1.8.3, installed from prebuilt ARM6 binary
- export GOROOT="/usr/local/go"
- export GOPATH="/home/pi/go"

This may be because you are using the built in DNS resolver in Go, rather than delegating to the system name resolver. When you built gRPC, did you set CGO_ENABLED=1 ? You can check by setting GODEBUG=netdns=cgo when getting gRPC:

$ GODEBUG=netdns=cgo go get google.golang.org/grpc
