在 dist-upgrade 上：错误，pkgProblemResolver::Resolve 生成​​中断，这可能是由保留的软件包引起的

在dist-upgrade操作过程中，我遇到了 apt 软件包的问题。

运行以下任何命令时，我遇到相同的错误：

$ sudo apt dist-upgrade
$ sudo apt --fix-broken install
$ sudo apt-get autoremove

错误：

我找到了3篇相关文章，其中的解决方案都没有解决我的问题：

在上面的问题中，他们似乎专注于特定的软件包，而不是发行版升级，所以我不知道如何简单地识别和删除有问题的软件包。

如果我尝试删除一个有问题的包，我会得到看起来像是一系列依赖项，这些依赖项会到达dist-upgrade，我想我不想弄乱它。

$ sudo apt-get remove gdm3

You might want to run 'apt --fix-broken install' to correct these.

我在这里找到了主要的 PopOS 升级线程：

https://www.reddit.com/r/pop_os/comments/ucge6e/upgrade_help_thread/

这些步骤为我解决了问题：

pop-upgrade release repair
sudo apt-get install -f
sudo apt-get full-upgrade --allow-downgrades

--allow-downgrades根据我遇到的其他资源，我特别缺少一些东西。
