AWS EC2 missing kernel modules. Can't install them?












0















Running ubuntu server 18.04 on an EC2 and for some reason, my linux kernel seems to be missing a bunch of critical modules. When trying to run ufw. I get this error:



ERROR: problem running iptables: modprobe: 

FATAL: Module ip_tables not found in directory /lib/modules/4.15.0-1032-aws


I checked in the /lib/modules/4.15.0-1032-aws folder and found that a bunch of stuff is missing from there that does exist in another instance I have running.



When I transfer the modules from my working EC2 to the broken one, everything works fine. However, if i restart the broken one, then the kernel modules get wiped again



Does anyone know what might be the cause of this?
