yum 如何支持sha256算法呢

youzhengchuan

我有一臺(tái)機(jī)器 yum 安裝軟件的時(shí)候提示：
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
dnidc/primary_db                                                                                             | 3.0 MB     00:00     
http://yum.xx.com/pub/repodata/5 ... primary.sqlite.bz2: [Errno -3] Error performing checksum
Trying other mirror.

Google 了一下，找到有人說(shuō)是：
以前createrepo使用的哈希算法是md5sum，現(xiàn)在隨著內(nèi)核版本的更新，默認(rèn)為sha256sum，

我看了一下我的repo.xml
curl http://yum.xx.com/pub/repodata/repomd.xml|grep checksum

但是網(wǎng)上的文章里面解決 辦法都只有在 createrepo 的時(shí)候加 -s 選項(xiàng)，可是這個(gè)yum源又不是我們能控制的，請(qǐng)問(wèn)有什么辦法可以讓yum支持”sha256“的checksum 算法。

謝謝~
