If the transaction check error occurs during Yum software installation, it indicates that the RPM software package has a conflict. The solution is as follows:
VI/etc/yum. Repos. d/epel. Repo
Change enabled = 1 to 0 and run: Yum List Installed | grep docker.
Docker-client.x86_64 2:1. 12.6-61. git85d7426. el7.centos @ extras
Docker-common.x86_64 2:1. 12.6-61. git85d7426. el7.centos @ extra
Just delete the above
[[Email protected] lib] # rpm-e docker-client.x86_64
[[Email protected] lib] # rpm-e docker-common.x86_64
Then, check getenforce. If it is enabled, disable it, and then re-install the software you want to install in yum.
