Install Mirantis Container Runtime for Oracle Linux

Docker
#1

Hi there, I’m having an issue installing Mirantis Container Runtime.
Anyone faced this issue as seen on the picture, even tried to install on Ubuntu on CentOS 7, and I’m tracking the steps on the Mirantis step by step, but it’s the same issue.

The problem is:

> WARN [0000] Some kubernetes kernel features are unavailable: unable to verify kernel features: Problems checking for kubernetes system recommendations: no contrack kernel modules (nf_contrack, xt_conntrack) loaded

Moreover:
I installed (nf_contrack, xt_conntrack) and configured ‘/etc/modules’, ‘/etc/modules-load.d/modules.conf’, but still !!

You’ll probably need to go to Mirantis support for this; I don’t think anyone here has experience with their CRI. You won’t have much luck with CentOS 7 though; that’s pretty much dead as a doornail, since the various repos used to install software were taken down by RedHat last year.

I solved, used Ubuntu 22.04
