就在前天，我的Fedora 8系统在安装SKYPE 2.0的时候，我才发现我的Fedora 8软件包更新工具出错问题，我当时在网上搜索了没有看见有人能解决本问题，于是我就只有自己解决，并写了本文章，希望能帮助那些遇到同问题的人解决问题！
我先测试了是不是加入的原的问题，同时也删除过YUM的配置文件并又上他自动生成过，还是不行，这证明了网他们说加入了freshrpms的yum源出问题的一说法是错误的,和其他源出错的问题，我就想是不是因为“fastestmirrort”和“Fedora 8软件包更新工具”之间的问题呢？我想在安装fastestmirror的时候，他会去改一个yum.conf配置文件plugins=1，于是就改过来一试就OK了，
运行Fedora 8软件包更新工具出现下面错误，或同类错误

问题出现的原因是，安装yum-plugin-fastestmirror(自动挑选快的镜像站)这个插件，他把这个文件/etc/yum.conf里面的plugins=1改成了1，所以就使得Fedora 8软件包更新工具出现错误我们只要把这个改成plugins=0
过程如下：
运行终端输入 su
输入密码:
gedit /etc/yum.conf
打开文件后，找到plugins=1这个把值改成plugins=0，保存退出就行了！
现在就可以使用Fedora 8软件包更新工具了
如果你使用YUM命令来更新，你还是可以把刚才改了那个值又改回来，又可以让他自动选择最快的的镜像站了，我一般是使用的yumex图形前端来安装软件，这样比较方便，但是向安装SKYPE2 for linux这类的软件就会出问题，所以只要按我说的做，就一定可以解决问题！
原创谢谢大家支持！
