I currently have OH 2.5 (OpenHabian) on my pi. I’d like to wipe out 2.5 do a complete fresh 3.0 install. I have never tried to do a clean install since I used an OpenHabian card image, and then just the automated updates ever since. I do not see any instructions anywhere to for how to do a clean install of OH3-RC1. The instructions for snapshots and milestones are for different repositories.
It seems like there must be more to it than just this:
Can’t answer this reliably as I don’t use them in my current test-environment - but I can tell that there is a nice standard graphing tool based on rrd4j persistence already integrated, which should suit the most common needs.
I’d start with a fresh new SD Card and use openHABian, which provides already a openHAB3 (milestone or build) option with sudo openhabian-config.
then do as described as above.
and then here
I myself switch from textfile-based configuration (OH2) to UI-based configuration (OH3) and therefore don’t migrate something, but built anew from scratch, also to get rid of some old f$%ked up namespacing of items and stuff and I move to the new Model-based approach, which I really like…
so basically I already started a few weeks back with the milestones and learned by doing. OK, I do have a whole bunch of Pis to do my tests, and my “old” OH2 still runs as main instance and will until I finally pull the switch to OH3…
Well that got as far as step two before the first failure.
[03:41:56] openhabian@openHABianDevice:~$ sudo openhabian-config
[sudo] password for openhabian:
openhabian is not in the sudoers file. This incident will be reported.
Unless there is some other user with rights, I assume I will need start over reburning the SD card?
Update: Burned image and redid install, same problem. Dead stop at step one since there is no way past this I can see.
