Possibility of building in kivy virtual machine all locally

[aminrasekh]

Is it possible to set up and version (freeze) the environment in kivy virtual machine such that builds can be done all locally (no internet connection) and thus consistently and reliably (independent of later dependencies updates, external changes, etc)?

We had set up a kivy virtual machine environment that worked all fine until just recently. Here is the virtual machine: https://pylie.com/dl/PylieBoxV1.7z

This build command used to work fine but now throws the error below.

kivy@kivy-VirtualBox:~/Desktop/Pylie/FlyPylie$ buildozer -v android debug

---

Some context: We use Kivy Virtual Machine in public educational programs for kids and teenagers.
Given our students have limited technical knowledge and are diverse and distributed, we need a virtual machine environment in which buildozer can do build runs consistently and reliably.

I just noticed the Kivy Virtual Machine is completely updated in your website. I am using it now and if it meets the needs explained above I go ahead and close this issue.
