Hi! I was needed to update falco in kubernetes cluster and i get error due to the url link to download prebuilt module is not found. How i can workaround/fix this issue? I deployed falco from yaml and tried several version include latest, 0.17.0, 0.24.0 and etc.

I am getting the same issue trying to deploy this to Minikube.

Actually I fixed my issue by updating the version of mini-kube I was deploying to!

I resolved this problem by compiling prebuilt falco module my own as described here (https://falco.org/docs/source/), uploaded it to registry, and have set DRIVERS_REPO env to valid url of *.ko. Then it's works.
