FYI, I got the error message below a fresh install for a Pi B+ 512MB. Should I submit a bug report somewhere?

Internet access is required to start the DietPi Installation
(And it asked if I want to reconfigure the network settings.)
This is all I have as I’ve already fixed the error and it’s off the screen now. Good thing I got this much from browser history and such.
Ran nano /etc/apt/sources.list and changed it the following, then re-ran dietpi-software, and all is well.
