halo@ubuntu:/etc/apt$ sudo apt-get -f install apache2
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:
 apache2 : Depends: apache2-bin (= 2.4.12-2ubuntu2.1) but it is not going to be installed
           Depends: apache2-utils (>= 2.4)
           Depends: apache2-data (= 2.4.12-2ubuntu2.1) but it is not going to be installed
 atom : Depends: git
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
