Hi, I looked into the issue as it was listing the package for autoremoval. The issue actually is quite easy as tox made a transition back in August 2015 (2.1.1-2) that renamed python-tox to tox. This transition now dropped the transitionals in 3.7.0-1.
There was no bug in python-scales for that transition, but the fix is simple, just follow the rename will make python-scales build again. I have test built unstable and testing before the change and saw testing fail. The reason why unstable still works is that the old binary (actually transitional) was never removed. With the fix builds against testing works again. I'm attaching a debdiff and will look for a sponsor. -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd
