This isn't an Ansible bug, but I cannot update using a local mirror (apt-mirror).
If I use an external mirror (us.archive.ubuntu.com) the anisible update operation works fine.
I found plenty of users complaining about apt-mirror bugs and Ubuntu 18.04, but no solid solutions.
The mirror is basically not getting DEP11 files.
Failed to fetch [http://localmirror/ubuntu/dists/bionic/main/dep11/icons-48x48.tar](http://192.168.100.205/ubuntu/dists/bionic/main/dep11/icons-48x48.tar) 404 Not Found [IP: 192.168.100.205 80]\n
Any help greatly appreciated.
