docker - Docker容器由于apparmor而无法启动，为什么？

Question

我重新安装了Ubuntu 18.04。安装的唯一程序是docker。

但是，如果我尝试运行hello-world容器以测试安装，则运行失败:

docker: Error response from daemon: AppArmor enabled on system but the docker-default profile could not be loaded: running `/sbin/apparmor_parser apparmor_parser -Kr /var/lib/docker/tmp/docker-default847992402` failed with output: apparmor_parser: Unable to replace "docker-default".  Permission denied; attempted to load a profile while confined?

error: exit status 243.
ERRO[0000] error waiting for container: context canceled

系统上没有安装apparmor配置文件:

apparmor module is loaded.
0 profiles are loaded.
0 profiles are in enforce mode.
0 profiles are in complain mode.
0 processes have profiles defined.
0 processes are in enforce mode.
0 processes are in complain mode.
0 processes are unconfined but have a profile defined.

如何安装配置文件？并修复错误？

我正在尝试运行:

sudo docker run hello-world 

我通过以下方式安装了docker:

sudo apt install docker.io

系统是LXC虚拟服务器上的Ubuntu 18.04

要在LXD服务器上正确运行docker，请在LXC配置中的vServer外部进行一些更改。就我而言，我必须在托管人的仪表板上启用Docker支持。
