Can't initialize iptables table `filter': Table does not exist (do you need to insmod?)

Question

I'm trying to open up port 1900 for UDP in order for the Echo to be able to discover the HA Bridge using the following command but I get errors. What is the best solution to fix this?

pi@raspberrypi:~/hue $ sudo iptables -I INPUT -p udp --dport 1900 -j ACCEPT
modprobe: ERROR: ../libkmod/libkmod.c:557 kmod_search_moddep() could not open moddep file '/lib/modules/4.1.17-v7+/modules.dep.bin'
iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
pi@raspberrypi:~/hue $ sudo depmod
depmod: ERROR: could not open directory /lib/modules/4.1.17-v7+: No such file or directory
depmod: FATAL: could not search modules: No such file or directory

pi@raspberrypi:~/hue $ sudo apt-get install --reinstall linux-image-4.1.17

Solution 1

These commands solved the problem for me (change the versions respectively):

 601  ls -lha /lib/modules
  602  pwd
  603  cp -R /lib/modules/4.1.18+ /lib/modules/4.1.17+
  604  sudo cp -R /lib/modules/4.1.18+ /lib/modules/4.1.17+
  605  sudo cp -R /lib/modules/4.1.18-v7+/ /lib/modules/4.1.17-v7+
  606  sudo apt-get install rpi-update
  607  sudo iptables --list
  608  sudo iptables -I INPUT -p udp --dport 1900 -j ACCEPT

Solution 2

This is a common error on old raspberry pi devices specialy if you install any additional iptable plugins (in my case it was PSAD which is not quite a plugin it just read logs) ,Jalal answer is correct but it don't need those module coping and it skipped a few steps.

As error says , iptable or raspberry pi firmware needs to update , mostly firmware needs to be updated, so you need to install rpi-update and run it but you must gave execute permission to /sbin/depmod first.

All you need to do is :

sudo apt-get install rpi-update
sudo chmod +x /sbin/depmod
sudo sudo rpi-update
