Actually, I was getting the same error when I was trying to train my model using opencv_traincascade. After searching the internet for a while, I found out the problem was with the background descriptor file, which in your case is bg.txt, the file you're using in Ubuntu must've created on Windows platform. Try creating a copy of the same file in Ubuntu by creating an empty file and then simply copying the content of the file and giving it a different name under the same directory. It should definitely work. Cheers. For any further issues comment down below.
