Hi, i’m running 0.92.2 on a raspberry pi 3b+ and when i try to update i get:

core-ssh:~# hassio ha update --log-level debug

Any suggestion?

Same here…

Does the homeassistant log reveal anything?

No, when i execute hassio ha update nothing appears in home-assistant.log

Looking in the “System” tab of Hassio i found:
