erro ocorreu durante a instalação da biblioteca do PHP 7.0 GD no servidor ubuntu

Question

Quando tentei este comando:

apt-get install php7.0-gd php7.0

Eu recebi o erro abaixo:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libapache2-mod-php7.0 :
       Depends: apache2-api-20120211
       Depends: apache2-bin but it is not going to be installed
       Recommends: apache2 but it is not going to be installed
E: Unmet dependencies.
Try 'apt-get -f install' with no packages (or specify a solution).
