[Serious]Error on OpenVPN Startup-Help Requested(log attach)

superinterstellar

Hello,
I have finally managed to sort out all the other issues except one. The starting of tun0 does not seem possible.
I really would appreciate if someone could tell me what is the cause of this fatal error.
My log is below :-

You must run openvpn as root ... maybe use sudo ?

What OS is your machine ?
How did you install OpenVPN ?

superinterstellar

hi traffic,

yes. i am running as root
i am running 14.04.1(ubuntu)
i installed openvpn by running
apt-get install openvpn.

i just tried the following(to run as root0:

server02:/home/admin# service openvpn start
 * Starting virtual private network daemon(s)...                                                                                                                                                  *   Autostarting VPN 'server'                                                                                                                                                                  
root@server02:/home/admin# ifconfig

But nothing with tun0 shows up. I had this same problem the last time, cant remember how i got around it.
Apppreciate if someone could help.

Thanks!

As openvpn now has it's own repos for trusty .. you could try this:
