Custom CA Certificate on HASS OS

Configuration
1

Hi everyone!

I’m currently running Home Assistant OS in a virtual machine and need help installing a custom CA certificate. I’m using an internal Sonatype Nexus container image cache, and I’d like Home Assistant to trust my internal registry to avoid update failures.

In typical environments (e.g., standard Linux OS or Kubernetes clusters), I add the .crt file for my internal CA to the trusted certificate store. How can I achieve the same with Home Assistant OS? Is there a recommended way to add a custom CA certificate so that Home Assistant can validate connections during updates?

Thanks in advance for your help! :slight_smile:
