当我将 Ubuntu 从 21.10 升级到 22.04 时，遇到以下错误：
# apt dist-upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:

所有选项均失败。如何修复？
答案1
找到了解决方案（在连续两次遇到同样的问题后，两台笔记本电脑均从 21.10 到 22.04）
问题的唯一原因是使用 ubuntu 的 OS 升级 GUI（设置 -> OS 升级和恢复 -> OS 升级），此选项已损坏或仅适用于 Ubuntu，不适用于 Pop OS。
升级 Pop_OS 的正确方法只有 1 种，而且不通过任何 GUI：
sudo apt full-upgrade
这样做可以从头开始升级或从损坏的升级中恢复。
