Vlc not finding any UPnP devices

Disabling ipv6 worked for me.

Solution from here :

echo 1 | sudo tee /proc/sys/net/ipv6/conf/all/disable_ipv6

I found the answer.

You can download a new version of libupnp here

And install it :

cd Downloads
sudo dpkg -i libupnp6_1.6.19+git20160116-1_amd64.deb
