[Sjoerd Simons]

Source: etcd
Version: 3.1.2+dfsg-1
Severity: normal

When trying to build against the stretch version of
golang-github-xiang90-probing-0.0 the following error is seen:
  src/github.com/coreos/etcd/rafthttp/probing_status.go:54: s.Err undefined (type probing.Status has no field or method Err)

Please update the b-d to at least the required version of golang-github-xiang90-probing-0.0
