Here’s my solution:
sudo nano /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0
Just to make sure:
sysctl -w net.ipv6.conf.all.disable_ipv6=0
sysctl -w net.ipv6.conf.default.disable_ipv6=0
restart network:
sudo /etc/init.d/networking restart
Then:
sudo su
and then:
openvpn yourfile.opvn (no sudo here)
