 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

 

原因

yum源没有对应版本包匹配
 

解决方法

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sed -i  's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo
yum repolist
