Fix Not privileged to run udev monitor! in Ubuntu

There’s an annoying error in Ubuntu causing addons not being updated:
Not privileged to run udev. Update your installation!
This was discussed in Issue #1569 · home-assistant/supervisor (github.com).

Solution proposed by fzsombor(github.com)

You can always add -v /dev:/dev in /sbin/hassio-supervisor to the docker run command. This way udev symlinks will be exposed to the container and the error message disappears, updates will be possible. However, be aware that this way you expose real /dev inside the container.

Is there any other way to fix this issue except switching to Home Assistant OS and exposing all the devices to the container?
