今天在在用yum的时候出现下面的郁闷事情

[root@localhost ~]# yum install -y python python-devel

http://mirrors.163.com/centos/5/updates/i386/repodata/filelists.sqlite.bz2: [Errno -1] Metadata file does not match checksum
Trying other mirror.
Error: failure: repodata/filelists.sqlite.bz2 from updates: [Errno 256] No more mirrors to try.
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest

google baidu了大半天最好发现一个网友（

）有我类似的问题，说只要执行yum clean all就OK了，回去又看了一遍yum命令的参数，是有这个参数呢，不管三七二十一，试一下再说。

然后再yum就一切OK 了。
