docker run hello-world 失败，stderr : permission denied

Question

我已经通过 https://get.docker.com/ 安装了 docker过程进行得很顺利，但是当我尝试运行它时，我收到了错误

docker -D run hello-world:

Unable to find image 'hello-world:latest' locally

docker: failed to register layer: ApplyLayer exit status 1 stdout:  stderr: permission denied.
See 'docker run --help'.

我没有/etc/pve/lxc 文件夹，也没有可用的 lxc 命令 docker run hello-world still fails, permission denied似乎建议解决它。

我对这个错误失去了理智，请帮忙!

你可能错过了这一步

sudo usermod -aG docker your-user

注意这个:

NOTE: Remember to log out and back in for this to take effect!

正如 docker 告诉 stderr: Permission denied
