Don't know why is a -ng in the end as it was another package. Maybe I was confused whit another machine logged via ssh too and I finally came mixing them.Right now I have a lot of work and no time for this issue.

I typed "systemctl start apt-cacher-ng.service" and returns no error, so I assume it works ok. Just need to adjust configuration files. Thanks a lot about pointing my in the right direction (-ng)

What is the output of:

updatedb && locate apt-cacher

I installed a Debian virtual machine with enough disk memory available and Installed on it. From zero to functional installation 30 mins. Diagnose and repair this problem is above my skills, and I know that this package is not popular so waiting that someone in the future with more skills than me can find a solution.

apt-cacher works as a proxy for Debian (Ubuntu, raspbian, etc) packages, so the first time you download the package from official repos, then from clearos box.....

So this is useful when you have some raspberry pis behind clearos box
