Installing LinuxCNC 2.9 or Master on Linux Mint 21

I came across a link for upgrading the python on Mint 21 to 3.11 is that no longer needed for 21.1?
I can't seem to find an answer on line for that one.
www.linuxcapable.com/install-python-3-11-on-linux-mint/

For ease of use and simple installation, I would go with debian bookworm non free netinstall (CD image)

rod is that the one referenced on JT's site?

Possibly but I just found out this morning its changed on 23 Feb.
The non-free firmware is now included in the alpha-2 release and there were warnings telling me not to go to the non-free anymore
cdimage.debian.org/cdimage/bookworm_di_alpha2/amd64/iso-cd/

Debian's hard freeze pending Bookworm becoming the official relaease starts tomorrow so this is pretty solid.
then just preempt_rt will be installed during this install of 2.9.

The alpha-2 is what I used in the qtpyvcp-dev VM install - everything just worked.  No fuss.

I have just installed LinuxMint 21.1 'Vera' and compiled the latest 2.10pre (master) on a machine (without a realtime kernel).
After getting errors regarding python when starting linuxcnc i used the link provided by my1987toyota above
(forum.linuxcnc.org/9-installing-linuxcnc...-21?start=140#266317)
to upgrade python from 3.10 to 3.11 using the 'PPA-method' and can confirm that everything seems to be running fine.
I did have to install the openGL module using:
pip install pyopengl

Thanks

Hello Aciera, I have tried this method a few times and it still prompts that there is a problem with pyhon. Can you share your specific installation method?

Not sure what to say other than that I cloned the git repo for master and installed the missing packages according to the errors using
./configure --with-realtime=uspace --disable-build-documentation-translation --enable-non-distributable

until
make && sudo make setuid
went through with no apparent error but trying to load a config in linuxcnc would fail with errors that seemed so be related to python. Using the linked howto to update python to 3.11 and repeating the build process for linuxcnc gave me a working (simulation) setup.

$sudo update-alternatives --config python
on my machine now reports:
   
There are 2 choices for the alternative python (providing /usr/bin/python).

  Selection    Path                 Priority   Status

---

  0            /usr/bin/python3.11   8         auto mode
* 1            /usr/bin/python3.10   7         manual mode
  2            /usr/bin/python3.11   8         manual mode

 

it still prompts that there is a problem with pyhon

Where/ when does this prompt come up?
