有关如何诊断和解决此问题的指示？

Answer 1

从CentOS 8切换到流8指令只需点击几下下载页面

# Converting from CentOS Linux 8 to CentOS Stream 8                               
dnf --disablerepo '*' --enablerepo extras swap centos-linux-repos centos-stream-repos
dnf distro-sync

升级事务可以在不完全更新的情况下工作。

不要启用保险库，它只用于存档。离开安装它会鼓励使用寿命终止软件的不良做法。

显然，额外的回购存活了8和那里有发布包的流(和SIGs)的生活。
