码头:事务检查错误

Question

我正在尝试安装docker并遵循https://get.docker.com/

我在CentOS7上

-bash-4.2$ cd
-bash-4.2$ wget -qO- https://get.docker.com/ | sh
+ sudo -E sh -c 'sleep 3; yum -y -q install docker-engine'
Transaction check error:
  file /usr/lib/systemd/system/blk-availability.service from install of device-mapper-7:1.02.107-5.el7_2.5.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64

有人知道这个错误意味着什么以及如何解决它吗？

Answer 1

我更新了以下内容：

sudo yum update

现在，docker命令开始工作了

Answer 2

看起来device-mapper-7与系统上的lvm2-7不兼容。

您可以尝试卸载device-mapper-7。然后再运行一次Docker安装。
