error: reference to Debian is ambiguous;

My build.sbt:

import com.typesafe.sbt.SbtNativePackager._
import NativePackagerKeys._

name := """play-scala-test"""

packageArchetype.java_server

serverLoading in Debian := ServerLoader.SystemV

...

My project/plugins.sbt:

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.6" withSources)

You have the answer right in your error message

it is imported twice in the same scope by
import com.typesafe.sbt.SbtNativePackager._
and import root.com.typesafe.sbt.packager.debian.DebianPlugin.autoImport._

If you use 1.0.0-M1 I recommend using autoplugins. Your build.sbt looks like this

name := """play-scala-test"""

enablePlugins(JavaServerAppPackaging)

serverLoading in Debian := ServerLoader.SystemV
