HA Official Add-ons Repo update error

First, my apologies if this has been answered elsewhere. I did some searching and I haven’t found anyone running HassOS reporting this. It seems to be those who are running VMs, etc.

Initially I had installed the 32-bit HassOS rpi image on a raspberry pi 3 model B. A while back, around 0.112 and HassOS 4.13 (I believe), I made a full snapshot of my system and restored it to a new install of HA/HassOS of the same versions to a raspberry pi 3 model B+.

Now it’s about 4 months later and while investigating something else I noticed the following entries in the supervisor log on a routine basis. I assume this has been happening since the move to the new raspberry pi.

Does anyone have any suggestions on how I can proceed with debugging this? I’m relatively new to the container concept and the overlay filesystem so I haven’t had any luck via ssh trying to reset the local git repo clone by hand.

The official add-ons do appear in HA but I’m concerned they are not updating.

Thank you and take care,
