Apologies, the comment above should have read:

$ sudo apt install synaptic

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
 python3 : PreDepends: python3-minimal (= 3.5.1-4) but 3.5.3-1 is to be installed
           Depends: libpython3-stdlib (= 3.5.1-4) but 3.5.3-1 is to be installed
 python3-dev : Depends: python3 (= 3.5.3-1) but 3.5.1-4 is to be installed
 synaptic : Depends: libept1.5.0 but it is not going to be installed
            Recommends: rarian-compat but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
