Atualize o PHP de 5.3 para 5.6, dependências não atendidas

Question

Eu tenho um OVH VPS que executa o php 5.3. Eu gostaria de atualizar para o PHP 5.6. Eu usei essa solução ( Como faço para atualizar do PHP 5.3 para o PHP 5.4.6 no Ubuntu? :

sudo add-apt-repository ppa:ondrej/php5-5.6
sudo apt-get update
sudo apt-get install php5

mas tenho este erro:

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:
 libapache2-mod-php5 : Depends: apache2-api-20120211
                       Depends: apache2 (>= 2.4)
                       Depends: php5-common (= 5.6.18+dfsg-1+deb.sury.org~precise+1) but 5.3.10-1ubuntu3.15 is to be installed
 libapache2-mod-wsgi-py3 : Depends: apache2-api-20120211
 php5 : Depends: php5-common (>= 5.6.18+dfsg-1+deb.sury.org~precise+1~) but 5.3.10-1ubuntu3.15 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Você poderia me ajudar nas próximas etapas? Muito obrigado.

EDITAR

Quando executo sudo apt-get -f install , recebo o seguinte erro:

Acho que desinstalar o PHP existente primeiro deve corrigir o problema.

$ sudo apt-get remove php5*
