总是有个yumBackend.py阻止我用yum进行更新

【Another app is currently holding the yum lock; waiting for it to exit...】

上网查了，好像是说帮我安个桌面图标的进程。

估计是我没配代理服务器，所以一直拿着yum锁在那里运行，

直接用 yum remove PackageKit 删掉了事

参考

 

If you really don't like PackageKit, you can remove it by running the following command as root:

 yum remove PackageKit

You can also disable PackageKit from checking for updates by running gpk-prefs from the terminal:

 gpk-prefs &disown

In the preferences window, change Check for updates to never.
