Ubuntu 16.04 güncellemesinden sonra Python bağımlılığı sorunu

Paketleri yükseltmeye çalıştığımda aşağıdakileri alıyorum.

sudo apt-get upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
python : Depends: python-minimal (= 2.7.5-5ubuntu3) but 2.7.11-1 is installed
      Depends: libpython-stdlib (= 2.7.5-5ubuntu3) but 2.7.11-1 is installed
python-all : Depends: python (= 2.7.11-1) but 2.7.5-5ubuntu3 is installed
python-all-dev : Depends: python (= 2.7.11-1) but 2.7.5-5ubuntu3 is installed
python-dev : Depends: python (= 2.7.11-1) but 2.7.5-5ubuntu3 is installed
synaptic : Depends: libept1.5.0 but it is not installed
        Recommends: libgtk2-perl (>= 1:1.130) but it is not installed
        Recommends: rarian-compat but it is not installed
E: Unmet dependencies. Try using -f.

Setting up python-minimal (2.7.11-1) ...

dpkg: error processing package python-minimal (--configure):

Bu hatayı nasıl düzeltebilirim? 14.04'e düşebilir miyim? Bu konuyu takip ettim ama işe yaramadı. Önerilen komutu çalıştırdığımda aşağıdakileri alıyorum:

Şimdiden teşekkürler.
