octoklipper error: externally-managed-environment

[zaid-hm]

I'm trying to run klipper on a galaxy tab A (2019)
But when running the command in the instruction I get the following error:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/feelfreelinux/octo4a/master/scrip
ts/setup-klipper.sh)"
Setting up klipper
Do you have "Plugin extras" installed? (y/n): y

error: externally-managed-environment

× This environment is externally managed
╰─>
    The system-wide python installation should be maintained using the system
    package manager (apk) only.

    If the package in question is not packaged already (and hence installable via
    "apk add py3-somepackage"), please consider installing it inside a virtual
    environment, e.g.:

    python3 -m venv /path/to/venv
    . /path/to/venv/bin/activate
    pip install mypackage

    To exit the virtual environment, run:

    deactivate

    The virtual environment is not deleted, and can be re-entered by re-sourcing
    the activate file.

    To automatically manage virtual environments, consider using pipx (from the
    pipx package).

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

There is a new script for the 2.0.0 version of octo4a

https://github.com/feelfreelinux/octo4a/blob/master/scripts/setup-klipper-moonraker.sh

By the way i'm still figuring out, how to get it to work i'm running network error.
Maybe you should install 1.2.6 version of octo4a and use the command line you did.

[zaid-hm]

@Bartouzz did you manage to get it to work, I'm running into a network issue as well

[Bartouzz]

@zaid-hm Still not ... Starting to lose hope, see my current klippy log:

mcu 'mcu': Starting serial connect
mcu 'mcu': Unable to open serial port: [Errno 13] Could not exclusively lock port /dev/ttyOcto4a: [Errno 13] Permission denied
webhooks client 489798200720: New connection

mcu 'mcu': Unable to open serial port: [Errno 13] Could not exclusively lock port /dev/ttyOcto4a: [Errno 13] Permission denied

seem's like permission problem but i can't find the right answer. i'll post if get something

EDIT: If someone can help...

I'm working on this issue, am updating the klipper install script to work with octo4a 2.0
Once I've done some testing will provide the details for you to confirm.

I've fixed the environment and permission denied error, but have run into the next error (non rooted device) https://github.com/schmttc/octo4a/blob/schmttc-patch-1/scripts/setup-klipper.sh
Have confirmed that Klipper on a Raspberry Pi 3B is working with the printer.

[schmttc]

I've used setup-klipper-moonraker.sh and reduced it to only install Klipper, which resolves all issues.

Please try https://github.com/schmttc/octo4a/blob/klipper-fix/scripts/setup-klipper.sh

Note, you will get this error in klippy.log if Klipper is not set to the correct serial port, or the printer is not available/powered off. This error will go away once the printer is connected and configured correctly.

This may need more troubleshooting, while everything kicked off OK either Octoprint or Klipper crashed part way though a test print
