I have installed dropwatch using snap on Ubuntu 20.04. Running Kernel is 5.4.0-200-generic

When I run: dropwatch -l kas

I get: Unable to find NET_DM family, dropwatch can't work

I have checked the kernel var CONFIG_NET_DROP_MONITOR and its already set to y. Any ideas? Thanks.

I'm guessing its some kernel misconfiguration. I just tried on 22.04 with kernel 5.15.0-122 and it works fine. Perhaps you're looking at the config for a newer kernel but running a version that doesn't have it enabled. Suggest opening an issue with ubuntu.

Thanks for the quick reply. Hmm seems to be the correct Kernel I'm checking. I'll do some more digging.
