When running my puppet scripts to install Sensu I get this error:
Error: Could not update: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install sensu' returned 100: Reading package lists...

E: There are problems and -y was used without --force-yes
Effectively, it is failing when trying to run 'apt-get update' and 'apt-get install sensu'
However when I run these commands in the ubuntu terminal after it has been provisioned using vagrant the commands both work.
