由于我的存储库列表中出现了一些意外的折衷主义，该软件包fedora-release已从我的计算机（Fedora 21 笔记本电脑）中卸载并替换为generic-release.
但是，我似乎无法删除它：
[root@linuxbox ~]# yum remove generic-release
(...)
Error: Trying to remove "systemd", which is protected
也不安装 fedora 软件包：
[root@linuxbox ~]# yum install fedora-release
Loaded plugins: langpacks

如何替换generic-release为fedora-release？
答案1
你可以试试：
yum swap generic-release fedora-release
或者你可以尝试：
yum shell
> remove generic-release
> install fedora-release
> run
如果它不起作用，您可能可以下载正确的rpm软件包fedora-release fedora-release-notes并运行：
rpm -e --no-deps generic-release generic-release-notes
rpm -ihv fedora-release-*
