Subject: Re: [jmriusers] Experimental "Flatpak" distribution of JMRI

This seems like a "solution looking for a problem", at least for *Linux*.
Since JMRI is in JAVA and requires nothing outside of JAVA's JRE and
installing a suitable JRE under Linux is "trivial" (compared to MS-Windows or
MacOS), I am not sure how truely useful or needful this is.

I can see a flatpak (or similar) for MS-Windows or MacOS, since it appears
that those two O/S's have the greatest problems with installing JMRI, mostly
caused by confusion about installing the proper version of a JRE.

*I* would find a Linux "Flatpak" distribution of JMRI to be far more hassle to
deal with than the current Linux distribution methodolgy of JMRI. Actually, I
expect that the current Experimental "Flatpak" distribution of JMRI won't work
on my machine(s) anyway -- I expect it is a x86_64 Flatpak and all of my
machines use ARM processors. And this brings up a *new* issue that will
complicate things: there would need to be *four* Linux flatpaks: ix86, x86_64,
armv7l, and aarch64.

My only thought about "improvements" in the Linux distribution of JMRI would
be the creation of .deb and .rpm distrubutions of JMRI. I realize that JMRI
will never be in any Linux distro repo and I understand why that is, but a
self-made .deb and .rpm with a proper openjdk-XX-jre depenency could be
helpful. *I* could probably help with creating the necessary control files to
help with this, if anyone is interested.

As an experiment, you can find a 5.10 distribution in this form at



For more on this, see JMRI/JMRI Issue 11658:



Is anybody familiar enough with this distribution method to be able to try it?

Is this something that we should do on an ongoing basis?
