Hello everybody,
i´ve just switched to a new PC for my CNC router due to some memory issues, so with this new start i´ve decided to switch to Probe basic with python 3 and linuxcnc 2.9. i´ve had some issues with packages right from the getgo, after solving everything i´ve tried starting PB and it thew this error: file attached
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
i really don´t know what to do, does anyone have any idea?
Thanks in advance to everybody

Update:
i´ve reinstalled the whole system again, now trying to start probe basic gives this error:
i´ve read online that this problem comes when Qt is not the 5.12 or higher version, so i´ve installed the 5.12 version but the problem remains.
I´m going mad with this

I'm installing everything using the installer found in the repository, every time it throws an error, i try the command in the terminal and try to fix what it misses. for example, it look for python 3.9 instead of 3.7, at that point i execute the same command changing 3.9 to 3.7
edit: on the same note, on the qtpyvcp requirements page it says that i need python3-vtk9. installing it through apt gives that it doesn't exist, downloading it anjd installing it with dpkg gives dependency missing, in some of them it looks for python 3.10 or higher. do i need to install it too?

you could use the script installer, it seems to be more dialed in, i think the isntaller is still lacking some things and needs more work.
the script installer i just ran this morning and everything works just as it should!
github.com/joco-nz/lcnc-bullseye-installer

if you have Python 3.7, you are not runnig Debian Bullseye. You need Python 3.9 and up for V 2.9
Run that script installer on a fresh install of Debian Bullseye.

So, i've come to a conclusion, finally i would say.
Following the installation from github.com/joco-nz/lcnc-bullseye-installer i've realized something. I was running LinuxCNC Buster using the linuxCNC 2.8.2 conversion process to linuxCNC 2.9. The truth is that i needed to start with a complete vanilla Debian bullseye to made it work. I've followed the instructions from the installer and managed to install everything in roughly 15 minutes. In the end i've installed Probe Basic with python3, started everything, installed some missing libraries with pip and than it finally worked.
Thanks everybody to have guided me through this process as a noob that i am.
