Cannot update from 1.4.0 to 1.6.1

[kthayyi2]

What is the problem?

Updating from 1.4.0 to 1.6.1 fails. Attempts made though web interface and manually through SSH terminal. Error message pop up:

The update did not finish successfully. Please consult `octoprint.log` and `plugin_softwareupdate_console.log` for details.

What did you already try to solve it?

Connected to OctoPi through SSH terminal and ran the following code:

apt get update 
apt get upgrade 
~/oprint/bin/pip install -U octoprint

This did not complete succefully either, but Octoprint continued to function after restarting with

sudo service octoprint restart

Have you tried running in safe mode?

Yes. Resulted in failure with the same error message pop up

Did running in safe mode solve the problem?

No. Did not solve problem.

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Ah, the good old rogue logging module installed by some plugin strikes again:

Can't update from 1.4.0 to 1.5.3 : cannot import name NullHandler

Try ~/oprint/bin/pip uninstall logging from SSH in the terminal. Do you have the PrintTimeGenius plugin?

edit Now also on the FAQ:

My OctoPrint update fails with "ImportError: cannot import name NullHandler"

Earlier versions of the third party plugin PrintTimeGenius pulled in an unneeded third party logging module that is incompatible to Python's standard library. Its presence causes this issue. PrintTimeGenius has since been updated to no longer pull in this disrupting dependency, but if you installed an older version of it at some earlier point it will still have pulled it in. The fix is to manually uninstall logging from you OctoPrint venv via pip uninstall logging. For OctoPi: SSH into your …

@kthayyi2 next time, please also include how the manual install through SSH failed. You thankfully also included your plugin_softwareupdate_console.log which I could see the actual error message in, otherwise this would have been a case of another roundtrip just to get enough info from you to help you.

Thank you so much for such a quick reply! Your solution worked!

Yes, I did have print time genius installed.
I have now uninstalled logging (via SSH terminal)
I then restarted my OctoPrint server (via SSH terminal)
Then, through the web interface, I tried updating OctoPrint to 1.6.1 and it worked!

Once again thank your for all your time and effort into OctoPrint and OctoPi!
