Centos8安装docker的时候报错：Error: Problem: problem with installed package podman-1.0.0-2.git921f98f.module_el8.0.0 58 91b614e7.x86_64 package podman-1.0.0-2.git921f98f.module_el8.0.0 58 91b614e7.x86_64 requires runc, but none of the providers can be installed
原因：因为centos8中已经安装了podman容器，再安装docker的时候会报以上错误
解决方法：podman卸载就ok了 [root@bogon yum.repos.d]# rpm -q podman //查看是不是安装的有podman podman-1.0.0-2.git921f98f.module_el8.0.0 58 91b614e7.x86_64 [root@bogon yum.repos.d]# dnf remove podman //移除podman之后再安装docker
