Linux执行yum安装提示Another app is currently holding the yum lock； waiting for it to exit.
小课堂：
问题描述：
Linux系统中使用到yum命令报错：
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: yum

State : Sleeping, pid: 29635
解决办法：
输入：
rm -f /var/run/yum.pid
然后重新运行刚才的yum命令即可
原因:
可能是系统自动升级正在运行，yum在锁定状态中，要等待那个进程结束退出:
看报错的那一段话：
Another app is currently holding the yum lock; waiting for it to exit...
你可以看一下是否有yum进程
ps aux|grep yum
