我正在尝试更新 update-notifier 和 update-notifier-common，但却收到此错误消息。我应该怎么做才能修复损坏的更新？

有这8 年前有人说要重新安装 python-debian，但 apt 说包不可用。我担心安装 python 时做错了，因为修复起来似乎很麻烦。
如果这相关的话，我在使用 Xubuntu 21.04。

你必须跑
sudo apt-get update
sudo apt-get install --reinstall python3-debian
然后使用以下命令安装所有升级
sudo apt-get --fix-broken install
sudo apt-get dist-upgrade
