我们在工作中有一个运行 Gentoo 的旧开发服务器。我想更新这个系统，但我一直遇到打包系统的问题。对我来说，它似乎依赖于各种软件包的多个版本，我不知道如何修复它。
最大的问题可能与 Python 和 Portage 有关。我需要更新的 Portage，但似乎存在循环依赖关系。
我尝试过各种解决方案，但不太确定从这里开始。有什么线索可以帮助我进一步修复它吗？

几天前我也遇到了同样的问题。我不知道该怎么做，但这里有一个通用的方法：
首先看一下/var/lib/portage/world。备份并将软件包精简为系统启动所需的软件包。以下是一些内容，可帮助您入门：
app-admin/syslog-ng
net-firewall/iptables
net-misc/dhcpcd
sys-apps/pciutils
sys-apps/slocate
sys-apps/usbutils
sys-boot/grub
sys-kernel/gentoo-sources
sys-power/acpid
sys-process/vixie-cron
virtual/inetd
其余所有内容将稍后更新。
最关键的部分是让 portage 和 python 更新到最新版本，所以让我们集中精力于此。
出现你的 portage 目录：
emerge --sync或者：
emerge-webrsync设置有效的配置文件
eselect profile list eselect profile set <x>逐步升级python/portage。
查看您当前安装的 portage 版本。将 portage 升级到比当前版本更高的版本（即使它被 ~x86 屏蔽），然后对 python 执行相同操作。升级 python 后，请确保运行
python-updater。一步一步地执行此操作，直到 python/portage 更新到最新版本。（您可以跳过一些小版本升级。您将亲眼看到哪些版本会导致编译错误，哪些版本会导致编译错误。）
一旦它们工作，就尝试安装一些其他软件包，因为它们可能会帮助您完成任务。
app-portage/ufed app-portage/autounmask app-portage/gentoolkit一旦 python/portage 更新完毕，您就可以恢复旧的世界文件并更新您的系统。
emerge -pvauDN world您可能需要致电：
emerge ... emerge --depclean revdep-rebuild在构建过程中多次。

如果问题出在 python 上，请尝试运行python-updater
注意，你可以通过命令选择当前版本的 pythoneselect
