问题描述:
今天想在虚拟机上重新安装docker
然后使用到yum命令报错:
Loaded plugins: fastestmirror, langpacks Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast Existing lock /var/run/yum.pid: another copy is running as pid 3797. Another app is currently holding the yum lock; waiting for it to exit... The other application is: PackageKit Memory : 131 M RSS (1.5 GB VSZ) Started: Sun Jan 10 07:07:44 2021 - 01:01 ago State : Sleeping, pid: 3797
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
