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." ubuntu@ubuntu:~$ lsb_release -rd Description: Ubuntu 15.04 Release: 15.04 ubuntu@ubuntu:~$ apt-cache policy network-manager network-manager: Installed: 0.9.10.0-4ubuntu15 Candidate: 0.9.10.0-4ubuntu15 Version table: *** 0.9.10.0-4ubuntu15 0 500 http://archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: network-manager 0.9.10.0-4ubuntu15 ProcVersionSignature: Ubuntu 3.19.0-15.15-generic 3.19.3 Uname: Linux 3.19.0-15-generic x86_64 ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 CasperVersion: 1.360 CurrentDesktop: Unity Date: Thu May 7 22:55:12 2015 IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback IpRoute: default via 192.168.0.1 dev wlan0 proto static metric 1024 169.254.0.0/16 dev wlan0 scope link metric 1000 192.168.0.0/24 dev wlan0 proto kernel scope link src 192.168.0.20 207.173.246.134 via 192.168.0.1 dev wlan0 src 192.168.0.20 LiveMediaBuild: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true WimaxEnabled=true ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: network-manager UpgradeStatus: No upgrade log present (probably fresh install) nmcli-dev: DEVICE TYPE STATE DBUS-PATH CONNECTION CON-UUID CON-PATH wlan0 wifi connected /org/freedesktop/NetworkManager/Devices/2 LANbeforetime 1fefef93-2d1c-41eb-ad55-3f6c234d7023 /org/freedesktop/NetworkManager/ActiveConnection/0 eth0 ethernet unavailable /org/freedesktop/NetworkManager/Devices/1 -- -- -- lo loopback unmanaged /org/freedesktop/NetworkManager/Devices/0 -- -- -- nmcli-nm: Error: command ['nmcli', '-f', 'all', 'nm'] failed with exit code 2: Error: Object 'nm' is unknown, try 'nmcli help'.
