Additional information about your setup

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:

Exception:
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

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

This is your issue:

Trying to update OctoPrint on OctoPi 0.16 gives me an "AssertionError" about "assert have_directory_for_build", how do I solve this?

There have been some reports that upon trying to update OctoPrint on an OctoPi 0.16 image the update can fail with an AssertionError and assert have_directory_for_build: 2019-11-06 06:10:58,806 !

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.

Upgrading your OctoPrint install to Python 3

If you are still running Python 2 and using OctoPrint 1.7.0+, you will start to see warnings like this: [image] You need to upgrade your OctoPrint install to use Python 3, as Python 2 is end-of-life and OctoPrint 1.8.0 and later will no longer support running using Python 2. In addition, there's at least 39 plugins that already don't support Python 2 and more will follow, that you won't be able to take advantage of. You should upgrade as soon as possible. How can I upgrade? The process is sl…

Thx for you reply

And yes, this seems to be it... But as I'm not very versed, what do you mean by:

"So you could ignore fixing the update issue, because it will be included in upgrading your install."?

Thx ^^

No. Follow the instructions for upgrading to Python 3, and that will include resolving any issues with regular updates.
