emerge抱怨被封包：我该怎么办？

我们有一个运行Gentoo的旧开发服务器正在运行。我想更新这个系统，但我一直遇到包装系统的问题。对我来说，似乎有各种包的几个版本的依赖关系，我无法看到如何解决它。

最大的问题可能与Python和Portage有关。我需要一个更新的portage，但似乎存在周期性依赖。

我尝试了各种解决方案，但不太确定可以从这里开始。任何可能让我进一步修复它的线索？

几天前我遇到了同样的问题。我没有确切的方法如何做，但这是通用的方式：

首先来看看/var/lib/portage/world。进行备份并将软件包拆分到系统所需的软件包以启动。这里有一些内容可以帮助您：

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

其他所有内容将在稍后更新。

最关键的部分是将portage和python引入最新版本，所以让我们关注它。

1. 出现你的portage目录：

   emerge --sync
   

   要么：

   emerge-webrsync
   

2. 设置有效的个人资料

   eselect profile list
   eselect profile set <x>
   

3. 逐步升级python / portage。

   看看您当前安装的portage版本。将portage升级到高于当前版本的下一个版本（即使它被~x86掩盖），然后对python执行相同的操作。在python升级之后一定要运行python-updater。

   这一步一步一步，直到python / portage是最新的。（您可以跳过一些次要版本升级。您将自己看到哪些版本会导致编译错误，哪些会导致编译错误。）

4. 一旦他们工作，尝试出现一些其他包，因为他们可能会帮助您完成任务。

   app-portage/ufed
   app-portage/autounmask
   app-portage/gentoolkit
   

5. 一旦python / portage是最新的，您可以恢复旧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python中的问题然后尝试运行python-updater 请注意，您可以通过命令选择当前版本的pythoneselect
