Currently i have a server running Ubuntu 14.04 on a LEMP stack, i was trying to enable UFW following this tutorial.

But after i run ** sudo ufw allow ssh**

I'm getting the following error:
ERROR: initcaps
[Errno 2] modprobe: ERROR: ../libkmod/libkmod.c:556 kmodsearchmoddep() could not open moddep file '/lib/modules/3.13.0-36-generic/modules.dep.bin'
ip6tables v1.4.21: can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.

Any ideas?

Run the following command and then reboot your droplet to fix it:

sudo apt-get install linux-image-$(uname -r)

That should install your Droplet's kernel and the corresponding modules on the Droplet.

It appears that you might have upgraded the kernel without rebooting. Try rebooting the server and trying again. If that fails, let me know.

    Hi, I have the same problem. I have rebooted the server, but the problem persist.

Have another answer? Share your knowledge.
