[Bug 1452941] Re: PPTP VPN fails to connect in 15.04, but works in 14.04/14.10

 

The work around for this for me has been to delete the IPV4 Route that I
had configured.

After looking at some of the recommendations at
https://bugzilla.gnome.org/show_bug.cgi?id=733296, I found a solution.
In 14.04/14.10, I originally had had to set up an IPV4 Route to get the
PPTP VPN to work. In 15.04, deleting that Route from the GUI
configuration settings solved the problem. After deleting that route,
the VPN has been able to connect.

Title:
  PPTP VPN fails to connect in 15.04, but works in 14.04/14.10

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  I can create a PPTP VPN connection and connect to a remote network in
  Ubuntu 14.04/14.10 (Unity live boot DVD) but the connection does not
  work in Ubuntu 15.04 (Unity live boot USB), even though I am using the
  exact same GUI configuration settings in the Network-Manager (I have
  confirmed this several times).  In addition to the live boot
  instances, the PPTP VPN connected without problems for me on my
  14.04/14.10 installs, but failed on a fresh harddisk install of Ubuntu
  MATE 15.04.

  The error that I get in a notification pop-up window when trying to
  connect on 15.04 is: "The VPN connection 'VPN connection 1' failed
  because the VPN service returned invalid configuration."
