What is the problem?
After upgrade Octoprint will not start. Hoping to not have to re-install. /usr/bin/octoprint no longer exists.
What did you already try to solve it?
Several restarts and trying to manually start the service
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
Running OctoPi and cannot determine Octoprint version , but the update was for the latest as of 2 hours ago
Ok, so it seems that Octopi installs everything under /home/pi/.octoprint and after adjusting the init.d script to the new location, I can kinda get things working. Octoprint starts in Safe Mode every time, and when I do a restart the service, I get the following entry in the octoprint.log:

UnboundLocalError: local variable 'plugin' referenced before assignment
One of your plugins is failing and causing this issue (your log looks like it is not from safe mode - does it start in safe mode?).
The fact that this stops the server from starting instead of just gracefully handling it is a bug that will be fixed in 1.3.12.
What plugins do you have installed? I see you have quite a number of them.
Also, no, you should not have to change anything in the init script and octoprint also doesn't install itself to .octoprint - that's where its settings live, not its program code. It would help if you could clarify the issues you ran into that made you change the init script (and in what way you changed it).
/usr/bin/octoprint also never did exist on OctoPi, the default file for the init script correctly configured things to use /home/pi/oprint/bin/octoprint.
[quote="foosel, post:3, topic:9824"]
/home/pi/oprint/bin/octoprint
[/quote] is where I changed the unit script to look, I wrote the wrong location here. Originally it was pointing to /usr/bin/octoprint.
So, is it possibly to downgrade Octoprint back to pre 1.3.11 to be able to upgrade all the plugins and try the upgrade to 1.3.11 again?
The init script is by default pointing there, but that gets overwritten by /etc/default/octoprint. Again, there should be no change at all to modify the init script in any way on OctoPi, everything should be correctly configured out of the box.
So I am not sure why I didn't catch that the variable was being re-assigned from /etc/default/octoprint, that was a dumb mistake on my part.
After downgrading back to 1.3.10 and restarting both octoprint and touchui services everything's back up as expected.
I will try to upgrade the plugins then try the upgrade to 1.3.11 again. Hopefully it's just an older plugin that caused the issue. If there's an easy way of exporting the list of plugins and versions I can paste them here for scrutiny.
Guess I should've just looked in the log first. Here's the plugins I have loaded:

I'd suggest to take a look into the startup log of 1.3.10 because I'm fairly sure it should log an error for the affected plugin there as well. Might help to narrow it down.
Yeah, more than I realized and so I did clean some of them, but the two offending plugins that were having errors during startup were DisplayETA and LED Strip Control.
So, I should be able to upgrade, but I guess it begs the question that why from 1.3.10 to 1.3.11 broken plugins crash everything, and the fix is planned in 1.3.12?
The upgrade took without an issue and everything seems to be working as expected.
