Pyrhon3 is in the main now and it's a meta-package which pulls 
python3.6 which itself installs just fine(And Python3.5.3 itself 
updates to 3.5.4-rc.
)
Problem occurs only when it (python3, python3-minimal) tries update 
from 3.5 .3-3 to 3.5.
Note: I also have Unity installed.

After partial upgrade number of packages it tries to remove has reduced.
