"python setup.py egg_info" failed with error code 1

What is the problem?
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-rRPNga

What did you already try to solve it?
source ~/oprint/bin/activate
pip install --upgrade pip
Also updated the Setuptools
Can't seem to get this issue to go away
It started when I noticed that update OctoPrint version 1.3.10 would say it installed instantly but after rebooting was still at version 1.3.9
OctoPi version 0.15.1
Creality Ender 3 Printer
OctoPi was purchased from TH3D pre-installed on the Raspberry Pi 3B+ all as one unit.

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
octoprint (1).log (30.0 KB)

The device has been working fine and wanted to add some plugins but thought updating to the latest version would be best first and then install the plugins

Any help would be greatly appreciated
Regards Gary

It's usually a good idea to let OctoPrint manage the pip version. That's a fairly dramatic leap, if you ask me. What's also odd is that the before version doesn't report itself surrounded by single quotes and the after version does.

|    pip: 9.0.3    # before
|    pip: '18.1'   # after

Not sure what you mean by this, to be honest.
