Error during update, disk space issue?

Hi, I keep getting this error while trying to update:

20-01-25 18:37:08 ERROR (SyncWorker_16) [hassio.docker.interface] Can't install homeassistant/raspberrypi3-homeassistant:0.104.3 -> 404 Client Error: Not Found ("no such image: homeassistant/raspberrypi3-homeassistant:0.104.3: No such image: homeassistant/raspberrypi3-homeassistant:0.104.3").
20-01-25 18:37:08 WARNING (MainThread) [hassio.homeassistant] Update Home Assistant image fails

Having read other threads I suspect disk space issues (I’m on raspberry pi) but I don’t know how to solve it, there’s nothing else than hass.io on that system.

Thanks
