我更改了我的默认 Ubuntu 源列表，将 dist 名称更改为 而不是，xenial因为artful支持已经消失。
我跑了：
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get autoremove
并且它成功更新了我的所有软件包（rabbitmq/nvidia/wireless-regdb 除外）。
我的问题是，现在我的很多软件包都坏了，如果不解决这些问题，我就无法安装。
以下错误：

我努力了
$ sudo apt-get clear cache
$ sudo apt-get install --reinstall <broken package>
$ sudo apt-get install --fix-broken
没有成功。
我需要这样做吗apt-get purge <broken package>？它说它将删除很多重要的软件包，当我尝试在 python3 上这样做时，我有点害怕

备份数据后安装新支持的 Ubuntu 19.10 版本。这是我的意见
