昨天晚上打算安装 VMware Workstation for Linux 的时候，由于发现文件太大，由于我的笔记本是用无线网卡上网的，速度非常慢，中途关闭了终端结束了安装，然后用 yum clean all 命令清除了已经下载下来的部分 rpm 包。今天晚上回家之后安装 Picasa for Linux 的时候突然出现了如下的错误：
Could not retrieve mirrorlist http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-9&arch=i386 error was
[Errno 12] Timeout: <urlopen error timed out>
Error: Cannot find a valid baseurl for repo: fedora
好像是我网速太慢，没有下载完毕 fedora 的 primary.sqlite.bz2 文件的缘故，详细如下：
[charles@localhost ~]$ su
密码：
[root@localhost charles]# yum install picasa

在网上搜索解决办法，也没有得到什么有价值的结论，但是用 yum update all 命令之后终于成功拉
[root@localhost charles]# yum update all

现在 primary.sqlite.bz2 下载成功了，一切正常，随意安装了一个 licq ，顺利安装成功！

为了验证是否还有问题，故意用 yum 安装 beep media player 试了一下，
[charles@localhost ~]$ su

Nothing to do
提示没有找到 beep media player 的安装包，不过 yum 已经没有问题了。真是瞎猫撞上了死耗子，嘿嘿
