LinuxCNC Install using MX Linux 19.4 - Geared Toward New Users - Discussion

I followed your guide and everything went well.
Had table working in just an AXIS basic setup. Then when I loaded the QTplasmac it breaks my LinuxCNC. Get errors when I try to open it. And it breaks my AXIS link that was working before. Probably going to have to start over as nothing works now.

I started a post about my specific error screens:
forum.linuxcnc.org/39-pncconf/46772-erro...launch-after-pncconf

Any ideas what I am doing wrong?

A year or more ago I went through the guide on a spare computer and everything went flawlessly.

My luck being as it is, when I go to do it today on my plasma computer, I encounter problems.

I get to this stage in the guide, where I have to enter this command in the terminal window:
/usr/lib/python3/distpackages/qtvcp/designer/install_script

but I get the error message:
beefy@mx:~
$ /usr/lib/python3/distpackages/qtvcp/designer/install_script
bash: /usr/lib/python3/distpackages/qtvcp/designer/install_script: No such file or directory

I followed that file path in the file manager, all the way to "install_script" and everything seems to be there, so no idea why it says no such file or directory.

Anyway I tried starting Linuxcnc and selecting one of the Qtplasmac sim configurations but get and error:

Qtvcp encountered an error.

you are missing a package:
python3-pyqt5.qtsvg

Thanks cmorley,

still having issues though.
I installed the package using:
sudo apt install python3-pyqt5.qtsvg

and it looks like it installed OK.

Got another error message when I attempted to run Linuxcnc, saying something about PyQt5.Qsci, so ran the command:
sudo apt install PyQt5.Qsci

and it seemed to install OK.

Tried to run Linuxcnc again but get the error message:

Qtvcp encountered an error.

I have no idea what QGLWidget is or what it means that it is not defined.

G'day Beefy! Long time no see.
About 12 months or more ago all hell broke loose with Linux when it migrated from Python 2.7 to 3.xx. lots of other things have happened since then.
I gave up on other  distributions and reverted to Debian Bookworm. Its only a few lines at the command line to get going.
So if you have not got your plasma working yet, You could blow it away and follow my how to
