FATAL: all hosts have already failed -- aborting

Solution

The solution is to just add the option of force=yes

  
apt: pkg={{item}} 
       state=installed 
       install_recommends=yes 
       update_cache=yes
       force=yes

which is equivalent to what we would have done manually on the terminal

  
sudo apt-get install some-deb -y --force-yes

Every time I use Ansible my admiration for it only increases, how well advanced concepts have been implemented in such simple ways!
