supervisor: Update fails: no such image: homeassistant/raspberrypi3-homeassistant

While trying to run hassio ha update I receive the following error:

Can’t install homeassistant/raspberrypi3-homeassistant:0.65.6 -> 404 Client Error: Not Found (“no such image: homeassistant/raspberrypi3-homeassistant:0.65.6: No such image: homeassistant/raspberrypi3-homeassistant:0.65.6”).

Obviously it also fails through the UI.

df -h shows me the following:

Docker versions: homeassistant/armhf-hassio-supervisor: 0.98 homeassistant/raspberrypi3-homeassistant: 0.60.1

From what I can tell, there’s plenty of space for the upgrade to use. So why is this failing?
