Error "Unable to connect to the Docker daemon. Is docker -d on this host?" after updating the Linux kernel

Question

I am using Ubuntu 14.04 with docker v1.8.2. Docker works long before that. Then I just upgraded my Linux kernel from 3.16 to 4.05, and now the dockers are broken.

docker images

simlw@sim-lw:~$ docker images
Cannot connect to the Docker daemon. Is 'docker -d' running on this host?

ps auxww | grep docker

simlw@sim-lw:~$ ps auxww | grep docker   
simlw    23085  0.0  0.0  15976  2276 pts/24   S+   13:12   0:00 grep --color=auto docker 

sudo docker -d

simlw@sim-lw:~$ sudo docker -d
Warning: '-d' is deprecated, it will be removed soon. See usage.
WARN[0000] please use 'docker daemon' instead.          
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
ERRO[0000] [graphdriver] prior storage driver "aufs" failed: driver not supported 
FATA[0000] Error starting daemon: error initializing graphdriver: driver not supported 

Does anyone know how to solve this? thanks in advance.

Note that I already read Unable to connect to the Docker daemon. Does "docker -d" work on this host? and Docker Daemon is not working , and both of them do not help me.
