CentOS 8安装docker出现requires Containerd.io >= 1.2

不管是按照官方文档还是使用以下的阿里云自动脚本安装，都会出现同样的错误。

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun


问题: package docker-ce-3:19.03.13-3.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
