Docker.service fails to start, error "failed to mount overlay: no such device" on Raspbian

I recently had a problem with my raspbian installation. Probably some upgrade messed up my SSD boot. After resolving it, I noticed that docker.service refuses to start. On the service's log it says

I wasn't able to find anything relevant online. Ideally I would like to avoid losing my docker images

Edit: The kernel version was 4.19.114-v7l+, however there were no modules installed for this kernel under /lib/module. Running a "sudo apt install --reinstall raspberrypi-bootloader raspberrypi-kernel" fixed it.

You might have made a kernel update and need to reboot in order to use the new kernel instead of the old one.

In case you have an old kernel, update the kernel.

Check if modules are installed for the kernel under /lib/module.

sudo apt install --reinstall raspberrypi-bootloader raspberrypi-kernel

should fix it.

I had the same problem in a VM on a Xen host, and fixed it by installing pygrub and its own kernel inside the VM: https://stackoverflow.com/a/71763164/1069083

Your kernel might not support overlayl2:

  1. Try to upgrade your kernel (check if it has support for overlay2)
  2. Or use another driver like aufs or devicemapper for Debian > 9, and overlay for Ubuntu.

NB.: devicemapper is tagged as deprecated for Docker.

https://docs.docker.com/storage/storagedriver/select-storage-driver/

After your changes, you also might have to remove /var/lib/docker before restarting the service.

Good luck !
