Error when trying to work with iptables or ufw. How to set up a firewall in this case?

Question

ubuntu

Installed iptables
sudo apt-get install iptables

Further ufw
sudo apt-get install ufw

Well and further that I do not try to make, for example iptables -L , pours errors. What is this nonsense and how to fix it? How do you set up a firewall in such a situation?

Perhaps iptables or your kernel needs to be upgraded.

Answer 1

Execute sudo depmod.
PS I recommend next time to ask Google first, and then here.
