我最近在我的系统上更新了 python2，现在每当我尝试更新或安装任何软件包时，都会收到以下错误：
sudo apt-get install -f

我尝试过更新和升级，删除 apport 并重新安装，以及再次更新重新安装 python2。我还尝试过重新安装 apport 并删除
/var/cache/apt/archives/apport_2.20.9-0ubuntu7.4_all.deb

我知道错误 126 表示软件包已损坏或不完整，并且我看到过一些解决方案需要强制删除软件包，例如，
sudo dpkg --remove --force-remove-reinstreq PACKAGE_NAME
但我担心删除可能对系统运行至关重要的 python 包，所以我犹豫是否要删除它们。
编辑
我已经解决了这个问题使用 Live CD 重新安装 Ubuntu，无需重新格式化分区。只需恢复已安装的软件包。
