I have gone through the output in install log but I am lost. I cannot see why iot is failing.
Have you tried running in safe mode?

The printer still works
Did running in safe mode solve the problem?

Installing build dependencies ... error
I'm not quite sure what's going on
Could be a software problem, your filesystem could be corrupted or your sd card could be broken.
If nobody else comes up with another idea I would suggest you just backup your Octoprint via the backup and restore function, flash a fresh OctoPi image and restore your backup.
That should fix all software and filesystem related problems.
Apologies for being a pain ... but what do you mean by backing up Octoprint, backup the /home/pi and sub-folders (home directory) or is it something more I need to backup ?
Where do i find instructions for flashing a new OctoPi image, i don't have any personal settings or data to back up so would not be losing anything if I just went to a fresh image apart from enabling static IP !
There's a backup section within OctoPrint's settings that will export all of your configuration and plugins. Instructions for flashing a new image can be found at https://octoprint.org/download.
I managed to solve this issue with a small workaround, facing it while upgrading from 1.4.0 to 1.5.3.
The issue comes from the logging module, so it needs to be uninstalled first.
pip uninstall logging
Then OctoPrint can be upgraded with the command. I might as well work from the UI but I haven't tried it:
The logging module? OctoPrint core certainly doesn't depend on anything like that, it only uses the built-in logging... Maybe an issue caused by some third party plugin dragging in this?
Great, it worked. However, it still complains at the end of the install ...
ERROR: pip's legacy dependency resolver does not consider dependency conflicts when selecting packages. This behaviour is the source of the following dependency conflicts.
octoprint-printtimegenius 2.2.7 requires logging, which is not installed.
Well, that at least explains which plugin is dragging in this weird dependency... I guess it's time to get in touch with the PTG author, ask them why they require this dependency and if there's any way to get rid of it, because apparently it causes issues due to a namespace conflict with Python's own standard logger. edit Done, see here.
Note that this an issue completely outside of OctoPrint itself and rather a problem with this specific dependency and how Python works.
