运行 dockerd 时，未在此主机上找到受支持的文件系统“overlay”

我正在尝试在 Ubuntu 16.04 上安装 Docker。

当我运行“sudo dockerd”时，我得到以下输出：

它告诉我“overlay”未找到受支持的文件系统。但是，overlay 应该从内核版本 3.18 开始安装

我在用着：

4.4.0-042stab139.1

有人能帮我吗？谢谢！

请通过此链接检查 https://github.com/moby/moby/issues/33689 如果您发现它没有帮助，请检查全新安装步骤（请考虑它的写法，您必须添加 docker repo 而不是 docker ubuntu16.04 repo，它对我有用）

  1. 添加 gpg 密钥
  2. 将 docker 仓库添加到 APT 源
  3. 更新系统
  4. apt-cache policy docker-ce//安装docker仓库
  5. 上述命令的输出将类似于候选键和版本表的显示
  6. sudo apt-get install -y docker-ce
  7. 检查docker状态sudo systemctl status docker
