I originally set up my Raspberry Pi using the information from this gentlemen's site.
I am looking for some assistance in doing the following to the JMRI installation.
- I would like to update the JMRI that is on the system but I am a novice Linux admin
- How to back up at a minimum the roster that I have.? I use Realvnc to run the raspberry pi headless but I really do not have it "network" to my windows computers?
- How to download the latest JMRI onto the raspberry and perform the JMRI update.
- copy the roster back into the correct location.
- Clean up install files after I am done with the update.
Looking for other things I should do to the system (operating system update? or should I just leave it as is).
Note: I am happy to post better specification for my system, but I could use some help with commands that tell me what version of operating system I am running and system specs (I think it is a Raspberry pi 3 but am not positive).? i.e. pretty much up to this point I built it and have simply used it to do JMRI work.
Thank you?
