Docker can't start container: "Key not found in store"

On Xubuntu 20.04.3:
This morning, I wanted to restart an already existing Docker container:
... but got this error message:
[SOLUTION]
On my setup, the /var/lib/docker folder is a mountpoint for a larger disk - which wasn't mounted automatically, so Docker saw an "old", underlying installation structure. Therefore it couldn't find its keys...
But "mount --bind ..." didn't help, because Docker needs to restart to load its stuff properly.
Anyways:
Make sure your /var/lib/docker is as sane as your setup requires it, then restart docker:
Then try starting the container again.
