Installing flatpack on raspbian system

[Bart]

I’m trying to install Firefox on a raspberry pi 4.

I’m getting an IP not found.  The system responds to a ping — so I’m guessing its a software failure on that node.  Who should I ask?  Posting to a mailing list seems odd, but I didn’t see anywhere else to go with this request.

Thanks,
