title: "go get google.golang.org/grpc" failing: unrecognized import path
body: <p>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:</p>
  
  <pre><code>[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-&gt;192.168.1.1:53: i/o timeout)
  </code></pre>
  
  <p>Meanwhile I am able to install other (non-google.golang.org) dependencies (for example go get github.com/asaskevich/EventBus) just fine. </p>
  
  <p>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:</p>
  
  <pre><code>[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.
  </code></pre>
  
  <p>This is weird. Also I have installed the same packages on another system np.</p>
  
  <p>My environment is</p>
  
  <pre><code>- Go 1.8.3, installed from prebuilt ARM6 binary
  - export GOROOT="/usr/local/go"
  - export GOPATH="/home/pi/go"
  </code></pre>
