From fb11164c4f71315c96ddf3de46ff4689a5bac59c Mon Sep 17 00:00:00 2001 From: Christopher Jones Date: Mon, 12 Dec 2016 20:18:17 -0600 Subject: [PATCH] [plugins] return err when failing remove Fixes a case where removing the plugin from disk would fail silently. Also moves pluginStore remove after we remove from disk, so 'docker plugin ls' doesn't isn't empty in case it errors out.
