我做了一件蠢事。我只是scp编辑了我的rpmforge将另一台（工作）机器上的 repo 文件复制到我的开发盒上，然后运行yum update.这产生了：

哎呀。我没有遵循指示。所以我删除了*rpmforge*其中的文件/etc/yum.repos.d/，并以正确的方式重新开始。一切都很顺利，直到我尝试另一个yum update：

我想我可以删除这些文件，但我想确保通过使用更大的锤子，我不仅仅是首先将我的系统分解成更小的碎片。
我应该如何解决这个问题？
答案1
尝试ntfs-3g-2:2011.4.12-5.el6.x86_64通过以下方式删除包：
百胜删除 ntfs-3g
查看哪些包依赖于这个包。如果 yum 删除软件包列表中只出现一个软件包，您可以放心地删除该软件包。 （笔记：如果您不知道软件包是什么，请不要按“Y”来删除软件包。）
在此之后去yum update。
答案2
清理yum缓存目录：
# yum clean all
然后，尝试使用以下命令降级软件包：
# yum downgrade fuse-ntfs-3g
从手册页：
downgrade
Will try and downgrade a package from the version currently
installed to the previously highest version (or the specified
version). The depsolver will not necessarily work, but if you
specify all the packages it should work (thus, all the simple
cases will work). Also this does not work for "installonly"
packages, like Kernels. downgrade operates on groups, files,
provides, filelists and rpm files just like the "install"
command.
或者，使整个系统进入已知状态（没有rpmforge包）：
# yum distro-sync
再次，从手册页：
distribution-synchronization or distro-sync
Synchronizes the installed package set with the latest
packages available, this is done by either obsoleting,
upgrading or downgrading as appropriate. This will "normally"
do the same thing as the upgrade command however if you have
the package FOO installed at version 4, and the latest
available is only version 3, then this command will downgrade
FOO to version 3.
