当我从 ubuntu 21.10 升级到 ubuntu 22.04 LTS 时，我看到以下错误。我在通知区域看到一个持续的图标，提醒我更新时出了点问题。当我尝试更新（如它所要求的）时，我收到以下错误。
The Package system is Broken
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
The following packages have unmet dependencies:
firefox-locale-en: Depends: firefox (>= 1:1snap1-0ubuntu2) but 99.0+build2-0ubuntu0.21.10.2 is installed
我有两个版本的 Firefox，一个来自apt，另一个来自snap。我卸载了来自的一个apt，但我无法卸载另一个snap。在删除其中apt一个时，我删除了 Firefox 目录，如和~/.mozilla和/etc/firefox和/usr/lib/firefox/以及/usr/lib/firefox-addons/sudo apt-get purge firefox
sudo snap uninstall firefox
