When I try to update, I get the following error message:
The update did not finish successfully. Please consult octoprint.log and plugin_softwareupdate_console.log` for details.
and the follwing red text in the dialogue:
Traceback (most recent call last):
File "/home/pi/oprint/local/lib/python2.7/site-packages/pip/_internal/cli/base_command.py", line 176, in main
status = self.run(options, args)
File "/home/pi/oprint/local/lib/python2.7/site-packages/pip/_internal/commands/install.py", line 346, in run
File "/home/pi/oprint/local/lib/python2.7/site-packages/pip/_internal/wheel.py", line 886, in build
The printer then restarts, and all works well, but updating always fails
However, you are still running Python 2 for your install. You won't have seen the warnings introduced by 1.7.x, but OctoPrint 1.8.0 will drop support for Python 2 and you need to update it. So you could ignore fixing the update issue, because it will be included in upgrading your install.
