I have the following .drone.yml configuration which worked really well on my local machiane, now I moved in to a ubuntu 14.04 server. When building the repo it throws Error: No such image: plugins/slack:latest

workspace:
 base: /go
 path: src/me.com/repo/repo

pipeline:
 build:
   image: instrumentisto/glide
   environment:
     - GOOS=linux
     - GOARCH=amd64
   commands:
     - glide install
     - go build
     - go test -v -coverpkg=./controllers ./controllers_test -coverprofile=c.out && go tool cover -func=c.out
   when:
     event: [ push, tag ]

   when:
     status: [ success, failure ]

This was due to a dns resolving issue in the server. Adding google nameserver resolved the issue
