VPN connection fails to connect after upgrading ubuntu 16.04 [on hold]
I have started using Ubuntu version 16.04 for a while. My problem occurs every time I upgrade Ubuntu.
The vpn connection works perfectly fine after the installation of the operating system, but as I upgrade the system for one or two times, the VPN connection fails in successfully getting established.
I tried changing to systemd as I thought it might solve the problem by doing what XModulo has described,but I gained no result.
I do not understand the meaning of the tail -f /var/log/syslog output, so I bring it here:
