当我尝试时dnf update，当我做任何事情时都会出现Python异常dnf install。这些是同时出现的新错误，可能与我昨天在工作中遇到的电源故障有关dnf update，尽管历史日志似乎表明它已经完成，但有一些错误，前停电了。
当前的完整错误dnf update：

答案1
导致此错误的最典型原因是尝试在所有内容均未更新的情况下安装软件包。这有时会导致引入新的依赖项，与磁盘上已有的包发生冲突，并且 dnf 不知道它应该更新那些原本不相关的包。
就您而言，这似乎是另一回事，因为您在运行更新时看到了问题。不过，这里的错误肯定是不同体系结构中的可用版本和已安装版本之间不同步。例如：
file /usr/share/doc/glibc/NEWS from install of
glibc-2.25-10.fc26.i686 conflicts with file from package
glibc-2.25-7.fc26.x86_64
添加换行符使这一点变得显而易见：它正在尝试安装较新的 i686 软件包，但不知道要更新较旧的 glibc。
我要检查的第一件事是查看您是否安装了 x86_64 glibc 的多个版本。如果是这样，请运行sudo dnf repoquery --duplicates查看额外的版本，并dnf remove --duplicates进行清理。 （这将保留属于最新软件包的文件，因此即使它尝试删除看起来很重要的东西也是安全的。）
如果情况并非如此，则可能只是您现在使用的镜像不如之前获得的镜像更新。在这种情况下，请尝试sudo dnf clean all再次更新。
如果那不起作用，您通常可以通过暂时删除所有 i686 软件包来解决此问题。系统将在没有它们的情况下运行，然后您可以进行更新，然后放回与 32 位应用程序兼容所需的内容。
如果您仍然遇到数据库错误，则可能在 RPM 级别遇到不同的问题 - 但请从上述开始。
答案2
dnf --installroot=/mnt/fedora我通过从实时 USB 启动并使用;克服了 Python 异常。包冲突不断出现，包括我尝试dnf remove --duplicates甚至尝试逐一删除包时出现的错误。所以我最终决定系统无法修复，并重新安装了 Fedora - 最后还开始设置 snapper，以便下次发生类似情况时可以轻松修复。
