Als erstes system Aktualisieren
sudo apt update && sudo apt upgrade
Pyton version überprüfen
python3 -V
Wenn Pyton nicht instaliert ist mit
sudo apt install python3
instalieren.
Folgende Python dependencies werden benötigt
sudo apt install python3-pip
sudo apt install python3-dev
sudo apt install python3-setuptools
sudo apt install python3-venv
sudo apt install git
sudo apt install libyaml-dev
sudo apt install build-essential
Checken ob alles up to date ist pip install pip –upgrade # minu minus upgrade
Bei Fehler das probieren: sudo apt-get -y install python3-pip
Ermitteln der IP Adresse: hostname -I
Jetz muss ein neuer User erstellt werden:
Als Beispiel: octo
sudo useradd -m octo
Password (Beispiel)
sudo passwd octo yourpassword
Gruppen zum User Hinzufügen
sudo usermod -a -G tty,dialout octo
User octo anmelden:
su octo
cd ~
cd /home/octo
mkdir OctoPrint && cd OctoPrint
Anlegen des virtual environment:
python3 -m venv venv
Achtung space zwischen den Punkten
. ./venv/bin/activate
pip install –no-cache-dir octoprint #install minu minus
Test der Insallation
su octo
cd ~
cd /home/octo
python3 -m venv venv
. ./venv/bin/activate
~/OctoPrint/venv/bin/octoprint serve
Start OctoPrint user Interface
localhost:5000
Vorbereitung zum Autostart von OctoPrint
Datei erstellen -> octoprint.default
cd Downloads
sudo nano octoprint.default

Wichtig: Nach der Installation über die Ubuntu Software Verwaltung auf den Button
Permissions klicken, sonst kann es vorkommen das z.B. gemountete Netzlaufwerke nicht geschrieben werden könne.
