The issue you’re running into seems to be caused by your python-cherrypy3 upgrade.
Basically, something went awry in cherrypy 3.3- 3.6 and they can’t figure out a way to solve this without severely impacting existing installations on the much more popular 3.2 (what Debian and most derivatives use).
In the end, it looks like the solution is to downgrade your python-cherrypy3, and you will be able to keep all the other upgrades you wanted for other packages, etc.
Using the instructions on my first link, you’ll want to:
service mineos stop
apt-get -y install python-pip
apt-get remove python-cherrypy3
pip install cherrypy==3.2.3
service mineos start
