诡异问题，关于yumex

ebill84

Errno -1] Metadata file does not match checksum，每次到update仓库yumex都会报这个错，而如果命令行用yum就没事，怎么回事呢？

是吗，我还以为，我这边yumex跟什么冲突了呢

所以我也学会了终端下操作 yum。

看来有问题的不少啊，估计应该是大面积的中招，网上查到一个对于metadata和checksum的解释，比较好懂，跟大家分享一下：

To reduce load, download.fedora.redhat.com (official host) contains the ~1kB checksum for the metadata. The metadata (usually ~1 - 2 MB) is downloaded off mirrors. After downloading metadata, Yum compares the two to make sure they're one and the same.
Now, think of this: download.fedora.redhat.com updates their metadata and checksums, so you're getting the new checksum. The mirror's cronjobs havn't gone yet, therefore no synching and the metadata isn't the newest, it doesn't match.

The solution is not to makecache; Although it may help it will take forever and still not 100% solve the problem. The main problem is not giving the mirrors enough synch time. Typically, cron runs every hour, and give it a bit of time to download the changes, so I'd say try running maybe 10 minutes after an hour and you'll have no problem (eg 3:10, 4:10, 5:10, etc...). If you get closer to :50 (3:50, :50, etc) you'll start seeing more syncing issues.

Again, this too isn't 100% perfect but more of a guideline. There's a lot of guesswork...

用命令行或kyum吧。
