[calicoctl missing modules] Module xt_icmp not found in directory /lib/modules/4.15.0-45-generic

[vasilinamatov]

Hi, could you advise if calicoctl is supported in Ubuntu 18 kernel 4.15.0-45-generic and Openstack Rocky?
The issue is that I’m unable to load some missing modules to modprobe.
For example:

root#: modprobe xt_icmp
modprobe: FATAL: Module xt_icmp not found in directory /lib/modules/4.15.0-45-generic

And the calico node checksum gives me the following output:

root#: calicoctl node checksystem

System doesn’t meet one or more minimum systems requirements to run Calico

Calico is supported on Ubuntu 18, but as you found you need to make sure that the necessary kernel modules are present (either compiled into your kernel or installed via modprobe).

Are you seeing something in particular not working? Or is it just the checksystem output. Calico tries to load necessary modules when it starts on a node.
