Hi,
I just installed Debian and after installation I had to install the wireless firmware. The wireless seems working normally but when I run a proxy app, I get this error:

Code: Select all

enable_ipv6(): no IPv6 enabled interfaces
resolv.conf contains these nameservers: 192.168.1.1

The wireless working and I'm now connected with it, ifconfig :

Code: Select all

but I can't see it in /etc/network/interfaces:

Code: Select all

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

Any help would be appreciated, Thank you!

Presumably you are using the default NetworkManager for which there should be no interfaces defined in etc/network/interfaces.

Shall I configure it manually? please tell me what to do shortly, thanks.

Go to settings, wifi, click the cog wheel next to your wifi network, find and enable ipv6

You can have NetworkManager handle interfaces that are defined in /etc/network/interfaces

As root, edit /etc/NetworkManager/NetworkManager.conf and change managed=false to managed=true

OK, thanks. Guess I should have written NM generally doesn't need interfaces defined in /etc/network/interfaces
Does managed=true mean that NM uses those defined in the file, or does it mean it ignores them? (I don't use NM on my daily driver).
