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."

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:/

Keep your route but use 0.0.0.0 as teh route gateway.

pptp vpn works on ubuntu 14.04 with kernel 3.13.x and 3.16.x, but doesn't work with kernel 3.19.x.
And it doesn't work by default, until insmod nf_conntrack_pptp.

I needed to load all three of these modules to get it to work: nf_nat_pptp, nf_conntrack_pptp, nf_conntrack_

Scratch that, loading the modules allows it to work with a *single* IPv4 route, but I get the same error if I try to connect with multiple roots. My NetworkManager output to syslog is attached.

This bug also affects me. The workaround to remove the gateway from the static routes (leaving it blank) works like a charm!
Basically, just go to your static route configuration (ipv4 tab > Advanced) and leave the gateway blank.
Status changed to 'Confirmed' because the bug affects multiple users.
