You are correct. I spoke with a few developers last night and the culprit is resinOS. If you installed hassio prior to July 2018 (0.73 and below), you are using resinOS with hassio. ResinOS does not contain D-Bus.
@dap35 you actually don’t have hassos, you have ResinOS if you started at v0.73. Updates do not add hassOS, you had to have installed 0.74+ then updated in order to have hassOS.
I started with hassio around 0.61.
So the only way to rectify this problem is to wipe and install from a current version of hassio with hassOS.
