【问题描述】：

yum -y install redhat-upgrade-tool preupgrade-assistant-contents

preupg --force

输出：

preupg: error: [Errno 2] No such file or directory: '/usr/share/preupgrade/README'
The command 'preupg --force' returned a non-zero code: 2

我在这里错过了什么？

【问题讨论】：

前面需要“sudo”吗？
这是在 Dockerfile 中。我认为我不需要 sudo 。

【解决方案1】：

我刚刚使用基于 Centos 6.10 的 Cloudera Express 的 Docker 映像遇到了错误。我所做的是手动创建 README 和 README.kickstart （是的，它都失败了）取自： https://github.com/upgrades-migrations/preupgrade-assistant/tree/master/doc

修复此特定问题后，该工具会失败：

preupg: error: [Errno 2] No such file or directory: '/root/preupgrade/result.html'

为了克服这个问题，我们必须删除现有版本的 openscap（我有 openscap 1.2）并从 http://dev.centos.org/centos/6/upg 安装 openscap-1.0.8-1.0.1 并重新升级。

yum erase openscap
yum install http://dev.centos.org/centos/6/upg/x86_64/Packages/openscap-1.0.8-1.0.1.el6.centos.x86_64.rpm
yum install redhat-upgrade-tool preupgrade-assistant-contents
