@tabesin, the pr #436 was not required and it is causing this error if you see the codebase the recipe array and INSTALL array is the same we are just adding another environment variable which has already been added just with a different name, so I think we should stick with what was done previously
Chrome is also not open-source and should not be an option for the ISO when we are already giving chromium as an option

@pranav1698 according to #121 we have give option for chrome also and for INSTALL array I was implementing the solution in my way but get busy in college stuff.

@rpotter12 I understand that but the same thing is happening with the recipe array you can check it on the codebase the response is already added
