Error response from daemon: Cannot kill containers, permission denied

I am unable to kill containers in docker.
Can somebody please help?
It gives me permission denied error.

Have you tried to search for the error message on the forum or on the internet? I just searched on Google and found a topic here on the forum:

It looks like AppArmor can give you error message like this, but on other operating systems it can something else.

I changed the topic title, since we have other topics about killing containers not related to this kind of permission issue.
