I run Ubuntu Server 24.04 LTS with k3s. I update my container versions every few months, though not everything I’m running all at once. I update the actual system packages via apt maybe once a year and end up nuking and re-installing everything every couple years on average. I deliberately block all inbound WAN traffic in my firewall and use k8s network policies to aggressively limit egress WAN connections because I’m aware that I’m bad about keeping things up to date.
