Add error handling?

[Gcenx]

More a feature request due to the issue I thought I had #50
Maybe later into the projects life add some kind of error handling

What do you mean by Error Handling?

In the case of my problem before, if its even possible I'm not sure.
Say the file can't be downloaded like for me post an error saying that instead?

The problem is too catch the content of the error. Basically, the exception would need to go through bash -> docker -> python

Seems that like way too much work.

Actually we are currently catching the progress of the build so it is not something impossible to do
