CentOS 8.0 安装docker 报错：Problem: package docker-ce-3:19.03.4-3.el7.x86_64 requires containerd.io >= 1.2.2-3

1、错误内容

package docker-ce-3:19.03.2-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
- cannot install the best candidate for the job
- package containerd.io-1.2.2-3.3.el7.x86_64 is excluded
- package containerd.io-1.2.2-3.el7.x86_64 is excluded
- package containerd.io-1.2.4-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.5-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.6-3.3.el7.x86_64 is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

2、分析原因

看上面的内容，说的是containerd.io >= 1.2.2-3 ，意思就是 containerd.io 的版本必须大于等于 1.2.2-3

3、解决

1、要么就降低docker 的版本

2、如果不想降低docker 版本，那么就更新 containerd.io 的版本

wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
yum install -y  containerd.io-1.2.6-3.3.el7.x86_64.rpm

  
  

然后重新安装最新版本的docker 即可成功安装

4、检查是否安装成功

docker -v
