CentOS Stream 8 - DNF 损坏 - 无法运行更新/升级

Question

我以为我已成功从 CentOS8 升级到 Centos Stream 8，但我始终无法让 dnf distro-sync 工作。现在 DNF 似乎已损坏，并且 dnf upgrade 引发了与 DNF 本身相关的 libsmartcols.so.1 的不满意依赖项。
dnf 发行版同步:
运行同步时，将显示以下内容:

Error: 
 Problem: The operation would result in removing the following protected packages: setup
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

我尝试了 --skip-broken、--nobest --allowerasing 等所有可能的组合来解决。尝试使用保险库版本，没有区别。所有旧的 CentOS 存储库都已删除，因此/etc/yum.repos.d/文件夹中的唯一存储库是 -Stream-。我目前没有安装任何 EPEL 存储库。
cat/etc/centos-release => CentOS Stream 第 8 版
服务器在重新启动后仍然存在，并且似乎可以正常工作。
运行 dnf -y upgrade -v 时，结果如下:

dnf -y upgrade -v

To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix the issue.
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

我已经尝试清理包(dnf clean all)，删除缓存文件，单独尝试更新/升级每个包等。我没有想法。
有什么建议么？

Answer 1

经过几个小时的尝试，我能够通过执行以下操作来解决它:

从另一台服务器复制 CentOS-Base.repo 文件

编辑 repo 文件以反射(reflect) vault.centos.org 的位置，关闭 gpgcheck

dnf 清理所有

dnf 安装 libsmartcols-2.32.1-28.el8

再次运行 dnf -y upgrade ，它起作用了。去搞清楚。
希望这将帮助其他有相同或类似问题的人。
