@Srijan-SS02 There's some issue with crio tests on 22.04. We would need to try on a Ubuntu 22.04 machine, reproduce and fix the problem.

We cannot merge this PR till then. Would you like to take it up?

Yup sure, but will definitely need your guidance on that. Really interested to work on this!

@Srijan-SS02 great to know that.

The steps would be something in line of.

Create a Ubuntu 22.04 VM. Use install k3s script but with crio variable.

Afair it's something like RUNTIME=crio ./path/to/install_k3s.sh

The spelling and casing could be different, you can verify things from the GH Actions workflow itself.

Try deploying KubeArmor on the same. That should be suffice. Because KubeArmor itself fails to install in the CI env.
