Résolu : Linuxcnc 2.9 avec Debian 10 probleme True Type Tracer manquant

Because 2.9 requires Python3, I never had any luck installing it on Debian 10. Its probably looking for packages that dont exist. Upgrading to Bullseye or Bookworm should work. 

I prefer Bookworm so you can install linuxcnc and PREEMPT_RT with:
sudo apt install linuxcnc-uspace
sudo apt install linuxcnc-uspace-dev

I will upgrade tomorow , I hope , on the cloned disk.
I will use this how to :
phoenixnap.com/kb/upgrade-debian-10-to-11

The danger in upgrading is you will have python 2.7 and python3 on the PC so there are opportunities for confusion.

Is it possible to delete python 2.7 before upgrading or after?

I don't know. I had such a problem trying to get v 2.9 running on buster over a year ago, I have never used Buster or v 2.8 since.
I hsve been using Bookworm or sometimes Bullseye using this script  github.com/joco-nz/lcnc-bullseye-installer

Interesting, I have noticed you mention this several times. I have run 2.9 on Buster in both VM's and on my plasma table config without any issues.
