Após uma atualização com falha, quando eu quero atualizar ou instalar qualquer pacote eu tenho esse problema
$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
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 installed
python3-dev : Depends: python3 (= 3.5.3-1) but 3.5.1-4 is installed
Depends: libpython3-dev (= 3.5.3-1) but 3.5.1-4 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
