I just upgraded to 4.6, but unfortunately now docker fails to start, even after reinstalling it.
I get the same issue as: Docker error "failed to mount overlay: no such device" storage-driver=overlay2
Running sudo dockerd gets me:
failed to mount overlay: no such device storage-driver=overlay2
The full output:
