我在我的 ubuntu 18.04 系统上安装了几个 python 并尝试卸载所有必要的并正确重新安装 python3.6

所以我删除了下面列出的所有文件夹，这whereis python可能是个坏主意。

现在，如果我运行sudo apt-get install python3.6它会返回

然后我尝试更新最小包，sudo apt-get install -f --reinstall python3.6-minimal但返回

我不是一个真正有经验的 linux 用户，所以我被困在这里。有人知道如何修复我的 python 安装吗？

我发现了有关缓慢内核启动的类似主题，但我的问题是我的系统需要 3 分钟才能加载用户空间

systemd-analyze给出以下输出

Startup finished in 4.247s (kernel) + 3min 743ms (userspace = 3min 4.991s
graphical.target reacher after 1min 35.812s in userspace

有没有办法确定究竟是什么花费了这么多时间？我在 VirtualBox 中运行 Xubuntu 18.04，我认为问题是在我扩大分区后开始的（包括重新创建交换分区）。

编辑：输出systemd-analyze critical-chain
