### Basic Information: Printer Model: Ender3Pro MCU / Printerboard:SKR Mini E3v3 `klippy.log` _Fill out above information and in all cases attach your_ `klippy.log` _file. Pasting your_ `printer.cfg` _is **not** needed_ ### Describe your issue: Hello, tried to install Klipper on my Ubuntu Octoprint pc and got the python-dev error. So I removed it from the install script to see what would happen and got a whole bunch of errors. I have both python 3.10 and 2 installed. It looks like Klipper isn’t liking the python3.10 virtualenv. Anyone know if there’s a working version for Klipper for python3.1? I’ve attached the terminal output in the attached text file.

Python 3 is not yet officially supported. Any special reason why you need to use it? ---

My Ubuntu has the latest version installed. I installed Python 2 but I couldn’t get Klipper to install as you can see by the text file. If I had nothing else installed I could have done a clean install but unfortunately I can’t. ---

Do the following: 1. Login to your klipper user’s ssh account (likely `ubuntu`) 2. Switch to the home folder 3. Run 4. If all ran without errors, revert the change to avoid marking your installation as dirty 5. Add the `ubuntu` user to the `dialout` group ---

Run ```auto sudo apt install python2-setuptools-whl ``` then repeat: ```auto rm -rf ~/klippy-env ~/klipper git clone https://github.com/Klipper3d/klipper sed -i 's/python-dev/python2-dev/g' ~/klipper/scripts/install-ubuntu-18.04.sh ./klipper/scripts/install-ubuntu-18.04.sh ``` ---

All fine, the warnings can be safely ignored. ---

Cool. So just proceed with these 2 steps and start the clipper setup as per the instructions from the site? 1. If all ran without errors, revert the change to avoid marking your installation as dirty - `sed -i 's/python2-dev/python-dev/g' ~/klipper/scripts/install-ubuntu-18.04.sh` 1. Add the `ubuntu` user to the `dialout` group - `sudo usermod -a -G dialout ubuntu` [https://www.klipper3d.org/Installation.html](https://www.klipper3d.org/Installation.html) ---

Yes, of course. Typically the standard user of a Ubuntu distribution is `ubuntu`, that’s why I assumed it. General remark: If you lack Linux experience, your results might be better if you choose some Klipper dedicated distributions like [Mainsail OS](https://github.com/mainsail-crew/MainsailOS) or [OctoPi](https://github.com/guysoft/OctoKlipperPi) ---

The Octoprint log isn’t useful. We need your klippy.log file to help. ---
