Title:
  cannot load legacy-only plugin

Status in network-manager-strongswan package in Ubuntu:
  Confirmed

Bug description:
  Strongswan isn't presented as an option when I want to add a VPN in
  NetworkManager (GUI), despite the fact that the latest network-
  manager-strongswan (1.3.1-1ubuntu1) is installed.

  From /var/log/syslog:

  May  4 13:42:16 workmate gnome-session[1833]: ** Message: vpn:
  (strongswan,/etc/NetworkManager/VPN/nm-strongswan-service.name) cannot
  load legacy-only plugin

  $ dpkg-query --status network-manager-strongswan | grep ^Version
  Version: 1.3.1-1ubuntu1

  $ dpkg-query --status network-manager | grep ^Version
  Version: 1.1.93-0ubuntu4

  $ lsb_release -rd
  Description:	Ubuntu 16.04 LTS
  Release:	16.04

  Could be related to #1570352, but since the error-message is
  different, I created a new bug report

  I found network-manager-openconnect had a same issue, upstream fixed
  this by porting the code to use libnm [1] and [2]
