By waiting until this transition has landed in the artful release pocket.
No packages are guaranteed to be installable using the -proposed pocket at
any given point, and you should absolutely not be trying to upgrade a
desktop install against the -proposed pocket.


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.
