To diagnose booting/WiFi issues, it can help to connect the Pi using HDMI to a monitor/TV so you can directly access it and see if it is doing anything. Note that different software image would have a different IP address to the old one in most cases.
As for the older system, it looks OK to me. Open the settings (wrench in the navigation bar) and you should be able to find the plugin manager under there.
I mucked around with the old image trying to get rid of the obsolete Python message.
The instructions say to install the new octopi using the Raspberry Pi image utility, which is what I haven’t been able to make work. It then gave an alternative of running a python script to do the update. The first problem was I needed at least Python 3.5 to run the script, so ….
I made a backup via the octoprint web ui, the I made a backup of the whole sd card volume using Disk Utility on my Mac
I installed a bunch of development packages using apt-get.
I got the python source code
I did the old ./configure; make; sudo make altinstall dance
tried to run the setup script, was told I needed to install some python package with pip
tried to install that package , was told I should update pip.
updated pip
installed the package
ran the setup script…
To be told that my version of octopi was incompatible with the script.
So I guess tomorrow I’ll need to borrow the display and keyboard from my Mac and hope that gives a clue as to what’s happening with the new image.
Yes, I haven't tested it with older versions of OctoPi and I set the limit because the Python version and system dependencies are not guaranteed to be up-to-date enough. I didn't expect anyone to go through all the steps to build Python from source on their Pi, if they could just install a new OctoPi image easier. To use the script you have to be on OctoPi 0.17.
If you have all the system dependencies installed, and you really want to use the script - note that I still really recommend installing the newer OctoPi image, 0.15 is kinda old, you could edit the version in /etc/octopi_version temporarily.
Other than that, we'll wait and see what plugging it in to a display can tell us.
Thanks again. I hooked the HDMI up to the family room and it showed that it booted, showed it’s IP address and a login prompt.
It didn’t seem to be advertising octopi.local on Bonjour, but I could access it via the IP address and get to setup, After that it did show up on Bonjour.
I managed to then updated octopi to 0.18.
Next step is to take it back upstairs, connect it to the printer, and add some plugins.
In the meantime, I’ve been designing a pretty sweet enclosure for the Pi which wraps around the front left corner of the printer, hides the usb printer cable, and has a SD card slot for the printer using a microsd to sdcard adapter cable. And of course I’m planning to add a camera mount.
