问题接踵而至，在这个过程中的解决步骤如下，参考链接2、3：
（以下黄色亮底为实际操作或输入命令）

1）在终端以root身份执行：

sudo modprobe vboxdrv

2）vboxdrv 没有生效，是Linux内核专门用于驱动virtualBox驱动，叫做virtualbox-dkms

为当前内核重新安装一个驱动

sudo apt install --reinstall linux-headers-$(uname -r) virtualbox-dkms dkms

3）提示进程被占用

于是重启电脑

在终端重新输入上面两条命令

4）提示dpkg was iterruoted,you must manually run ‘dpkg…

sudo dpkg --configure -a

配置 python 默认版本
查看已安装python

$ u82:~/Py_demo$ ls /usr/bin/python*
/usr/bin/python2  /usr/bin/python2.7  /usr/bin/python3  /usr/bin/python3.8

设置默认版本

$ u82:~/Py_demo$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
update-alternatives: 使用 /usr/bin/python2 来在自动模式中提供 /usr/bin/python (python)
$ u82:~/Py_demo$  sudo update-alternatives --list python
/usr/bin/python2
$ u82:~/Py_demo$ python -V
Python 2.7.18

Python2 dependency hell
You need to install the package python-is-python2 to make Virtualbox work. This will override your /usr/bin/python symlink, which you can force back to python3 using update-alternatives or by hand after the fact. That said, I don’t know why they can’t just list Python as recommended or optional dependencies instead of as a mandatory dependency. It can be done with the Debian package management system.
