No ip_tables module after kernel update
I have an Ubuntu 16.04 Droplet that was upgraded from the previous LTS. I went ahead and used the DO Kernel menu to update my kernel which was 3.18something to 4.4.0-28. Did the shutdowns and restarts and I indeed have that kernel now.
However, I do seem to be missing some modules, ip_tables is the one I’m aware of, because UFW doesn’t seem to work because iptables doesn’t seem to work.
Tried googling for the problem, but every solution I find starts and ends with “update your kernel”.
I did make a snapshot before doing the kernel upgrade, so worst case I could fall back to that, but I went through all this because I wasn’t able to remove images from Docker, so I read I needed a new kernel for the overlay2 filesystem which was supposed to solve all my problems.
