我正在尝试在远程Web服务器上安装Docker,但是我遇到了一个令人沮丧的错误。我已经多次在此操作系统上安装了Docker,但从未出现过这种情况。
当执行命令sudo apt-get install -y docker-engine
时,我卡在了这里,因为无法安装Docker引擎:
~# systemctl status docker.service
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

我将root用户添加到了组中,并找到了一个建议,要在/etc/default/grub文件中添加
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
,但是该文件不存在!我还尝试了
sudo apt-get install cgroupfs-mount
,但没有成功 :-(感谢您的帮助!
