我正在尝试将我的 Centos 8 服务器迁移到 Rocky Linux。我使用迁移脚本，但收到此错误：

[root@domain migrate2rocky]# ./migrate2rocky.sh -r

An error occurred while we were attempting to convert your system to Rocky Linux. Your system may be unstable. Script will now exit to prevent possible damage.

 A log of this installation can be found at /var/log/migrate2rocky.log

这是我的 repo 文件：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the #mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

rpm -qif /etc/yum.repos.d/CentOS-Base.repo 并找出此框发生了什么，导致 repo 文件不属于包。migrate2rocky.sh 的作者不支持将其与 repo 文件一起自定义使用。

您的 repo 取消了对 vault 的注释。Vault 是旧的不安全版本，应尽可能避免使用，而应使用常规更新 repos。除了这个挑战之外，migrate2rocky.sh 不能很好地处理启用 vault 或其他自定义的情况。

脚本会执行一些通常可疑的操作，即rpm -e --justdb --nodeps（dnf --setopt=protected_packages= 我认为这些是它在编辑 repo 文件，然后将新的 Rocky 发布包与等效 repo 文件交换）之前。由于这些是包管理器本身，因此操作比较棘手，并且通常依赖项不允许删除它们。

备份此主机后，考虑安装 CentOS Stream repo 文件，例如 dnf install /etc/yum.repos.d/CentOS-Base.repo 然后脚本也许可以继续。

作为替代方案，请准备好全新安装 Rocky。当自定义和数据恢复自动化时，这将不会花费很长时间。特别是与与包管理器斗争以完成此升级相比。

  • 我不熟悉数据恢复自动化，并且我运行了一些服务，例如：Postfix、Apache、Postgresql。编程语言如 Python、PHP 等。重新安装和配置所有内容会很费力

  • 如果您不准备进行全新安装和备份恢复，则您无法通过任何方法升级发行版。尤其是当方法类似于此脚本时，它会禁用安全措施来切换发行版。考虑接受培训或聘请某人提供帮助。
