Is this required to release VPN support?

[Pete Woods (pete-woods)]

Sorry, but I don't know how to fix this. We need someone who actually understands network manager internals, and the PPTP plugin.

[Pete Woods (pete-woods)]

I can confirm this works correctly on a desktop machine. So it's some kind of ARM / phone platform related incompatibility.

[Bill Filler (bfiller)]

We'll remove the support in vpn UI for now for pptp until this gets fixed so we can at least release openVPN support

Status changed to 'Confirmed' because the bug affects multiple users.
