preupgrade 问题

heiking

WIN7+F14双系统,准备从F14升级到F15.第一次用升级安装.

先yum update -y了一次.更新了几个包.
然后yum install preypgrade更新了preupgrade包.
然后执行preupgrade升级.

此时系统不停的开始下载.最后提示要我重启.
我重启了.但是....什么都没有发生....F14还是F14.

这是怎么回事?谁有HOW TO?

Fedora 14 -> Fedora 15
先导入15 gpg公钥
First install the new fedora 15 gpg key. You may wish to verify this package against https://fedoraproject.org/keys and the fedora ssl certificate.

rpm --import https://fedoraproject.org/static/069C8460.txt

Upgrade all packages with

yum update yum
yum clean all
yum --releasever=15 --disableplugin=presto distro-sync

    * Do not run this from within an X terminal. Testing shows that X might hang while updating bitmap font packages.
      不要在 X terminal 运行上述命令，测试显示X环境下升级字体包可能会导致X挂起。
    * There exist .drpms, but they don't match, due to a format change, so better disable the presto plugin.

这样升级会提示错误,就算我用 -skip--broken 也不能完全的升级.最后连X都进不去了.GRUB也提示没有升级到F15.

最后还是下了DVD刻盘了用DVD升级的.
