dockerd broken docker doesn't load docker image

[Dorian ROSSE]

Hello,

dockerd is broken,

docker works without It own docker image but I need,

when I run 'docker network list' It shows docker image but nothing in the docker container fedora window...

I have run this :

'grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0'

then I have reboot since this command line and the reboot dockerd is broken this next command line show the docker status : 

'dockerd -D -p /var/run/docker.pid'

I happen error : 

pid file found ensure docker is not running or delete /var/run/docker.pid

Thank you in advance to help myself run docker images or repair dockerd and load dockerd images.

Regards.

Dorian ROSSE.
