Trying to create Ubuntu Installation Media

Problem: Having issues trying to point to an Ubuntu image on a mirror for Installation Media. I’m not entirely sure how to set the URL.

Expected outcome: Be able to use the Ubuntu Installation Media during provisioning.

Foreman and Proxy versions:

Foreman and Proxy plugin versions:

Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]
(for logs, surround with three back-ticks to get proper formatting, e.g.)


I am currently using the following url as an installation media: Upon trying to provision a machine with this url, it looks like it tried to go to

I am currently using Foreman version: foreman-
Proxy: foreman-proxy-
Katello: katello-3.4.5-19

Any help would be greatly appreciated!

Use as Installation Media URL. Everything else like Architecture / Relaese will be set later on via Operating System or by the Provisioning Template.

Just wanted to update this for anyone looking for help. Due to a recent bug that will not be resovled (, you have to set the Release to xenial-updates to use the bug-free version of the netboot installer.
