So with that said I ejected the SD card and opened it on my Windows machine.
Then I created the directory structure you showed (/var/lib/connman/) in the SD root.
Next, using notepad made the wifi.service file with the contents you provided.
Ok since I didn’t see it in root I assumed it needed to be made.
Got ya I will proceed that way, thank you @fzinken !
Yes I am aware but the problem is they don’t have any keyboards or mice laying around (assume zero tech savvy) to interface with the RPi once it boots up so I was hoping to have all the settings done so all they have to do is discover the device over the network via the Kodi Remote app, which I can walk them through over the phone.
Not that there’s anything wrong with manually adding iit ahead of time, but I just wanted to chime in and say there should not be an issue with enabling wifi via My OSMC with a Kodi phone app. I just checked it right now with the official Kodi remote on iOS and I was able to navigate to enable wireless, choose my ssid, and when I told it to connect it popped up the virtual keyboard on my phone to enter the passphrase which transmitted that input to Kodi. No problems at all.
