ValueError: need more than 1 value to unpack python

This means that there is a line in packages.txt that, when you strip whitespace and split on commas, doesn’t give exactly three pieces. In fact, it seems that it gives only 1 piece (“need more than 1 value to unpack”), which suggests that there’s a line with no commas at all.

Perhaps there are blank or comment lines in packages.txt?

You may need your code to be smarter about parsing the contents of the file.
