Can't Update anything

After years of my setup working near flawless I seem pretty hosed. My z-wave stopped working as did my addons for duckdns and ssl. Any attempt to update anything fails with what seem to be docker related errors like:

http+docker://localhost/v1.41/containers/addon_core_duckdns/json: Internal Server Error ("readlink /mnt/data/docker/overlay2/{"Binds": no such file or directory")

And this from z-wave

Error updating Z-Wave JS: Can't install homeassistant/armv7-addon-zwave_js:0.1.93: 503 Server Error for http+docker://localhost/v1.41/images/create?tag=0.1.93&fromImage=homeassistant%2Farmv7-addon-zwave_js&platform=linux%2Farm%2Fv7: Service Unavailable ("error creating temporary lease: connection error: desc = "transport: Error while dialing dial unix:///var/run/docker/containerd/containerd.sock: timeout": unavailable")

Upgrading the Hass OS or core also fails.

Any tips? Or should I just start over?

my 2cts…check if the filesystem is full…

Filesystem shows only 19% full

Dns error perhaps.

How would I troubleshoot that?

nslookup would be a start.
