I run HASSIO as a Docker container on Ubuntu (running as a VM on my QNAP)

What you have is called Home Assistant Supervised. A summary of the four primary installation methods is shown here.

Home Assistant Supervised is officially supported on only one Linux distro and that’s Debian (for more information, see ADR-0014). All other distros are not supported (by the development team) and only by the community.

I don’t know the answer to your question but hopefully someone else in the community does. After it has been resolved, consider switching to Debian at your earliest convenience to avoid other operational quirks resulting from running on an unsupported distro. It shouldn’t take too much time because you are using a VM.
