我正在尝试安装chromedriver。
我正在尝试在虚拟盒子上。然后我切换到实际的盒子，但是遇到了同样的问题：
$ sudo apt install chromedriver
[sudo] password for michael:

Package chromedriver is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'chromedriver' has no installation candidate
