A lambda creates an anonymous function, and needs to know how many arguments to consume in case the installation script fails to download.

It is the difference between printing:

Code:

2016-07-04 15:11:16 ERROR 404: Not Found.
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: <lambda>() takes 0 positional arguments but 1 was given

and:

Code:

2016-07-04 15:10:39 ERROR 404: Not Found.
Download failed

tl;dr How many arguments did you pass into:
main()
main('/opt')
main('/opt', True)
