2.9 Install Help

I used the ISO and got an instance of 2.8 working on my machine with the parallel port. I liked QTDragon and would like to try out QTDragon HD, which requires 2.9 effectively (best I can tell). I'll also note that I'll probably try PathPilot down the road, but I want to get things worked out with QTDragon HD first. To assist in this move, I'll be adding a Mesa 7i92H soon, but for now I'm just trying to get the software installed / working.
So, I tried upgrading my Buster / 2.8 install to 2.9, and that failed miserably. I had over a hundred dependencies that I couldn't figure out how to resolve, so I started looking for other options. Here on the forum, I found the sticky for installing 2.9 on Mint (forum.linuxcnc.org/9-installing-linuxcnc...ter-on-linux-mint-21), so I've tried that.
I have Mint installed, and LinuxCNC 2.9 works in Axis. But I can't get it to work with QTDragon (any of them). I first had errors that PYQT5 was missing, so I got that installed (sudo apt-get install python3-pyqt5).
Now, when I run LinuxCNC with any of the QTDragons, I get this error:
When I hit "Retry", I then get the normal LinuxCNC Errors window:Traceback (most recent call last):File "/usr/bin/qtvcp", line 511, in <module>APP = QTVCP()File "/usr/bin/qtvcp", line 133, in __init__from qtvcp import qt_makepins, qt_makeguiFile "/usr/lib/python3/dist-packages/qtvcp/qt_makepins.py", line 22, in <module>from qtvcp.widgets.screen_options import ScreenOptionsFile "/usr/lib/python3/dist-packages/qtvcp/widgets/screen_options.py", line 24, in <module>from qtvcp.lib.message import MessageFile "/usr/lib/python3/dist-packages/qtvcp/lib/message.py", line 5, in <module>from qtvcp.widgets.dialog_widget import LcncDialogFile "/usr/lib/python3/dist-packages/qtvcp/widgets/dialog_widget.py", line 32, in <module>from qtvcp.widgets.macro_widget import MacroTabFile "/usr/lib/python3/dist-packages/qtvcp/widgets/macro_widget.py", line 86, in <module>class CustomSVG(QtSvg.QSvgWidget):NameError: name 'QtSvg' is not defined

I've googled as best I know how and haven't found any solutions related to LinuxCNC. I'm sure it's something simple, but I don't know how to fix it. Hopefully someone here does...
Thanks,
Danny

For newbies like me, what I did was:
cd /usr/lib/python3/dist-packages/qtvcp/designer/
sudo bash install_script
When prompted, I chose option #3 for package install (I guessed).
The base QTDragon now appears to work. But when I choose QTDragon HD, I get the QTVCP error window once it's loaded:
Traceback (most recent call last):File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 54, in paintEventself.draw_zones(painter, event, w)File "/usr/lib/python3/dist-packages/qtvcp/widgets/round_gauge.py", line 84, in draw_zonesrect.setSize(QSize(w/2, w/2))TypeError: arguments did not match any overloaded call:QSize(): too many argumentsQSize(int, int): argument 1 has unexpected type 'float'QSize(QSize): argument 1 has unexpected type 'float'
And after I hit "Abort" ("Retry" doesn't change anything - the error pops right back up) then I get the normal Linux CNC error box that contains:
I haven't researched this one yet, but Ifigured I'd post my progress here for future reference...Print file information:

Those all seem QT errors, so might get more help here.

can you;
open a terminal and type:
python3
then:
from PyQt5.QtCore import QT_VERSION_STR, PYQT_VERSION_STR
print("Qt: v", QT_VERSION_STR, "\tPyQt: v", PYQT_VERSION_STR)
And post what it prints.

I'm 99% sure that version has the changes that break out code.
Unfortunately I don't have a system that uses the new library so can't current test.
I have fixed the errors as best I can as they are reported.
I see errors from round_gauge in your post so will look at he code and see if I can fix it.

Is there a work-around? Can I downgrade something somehow for instance?
Thanks for the help,

So you could try checking for linuxcnc updates.
I know no way to downgrade the pyqt version on the system.
Only by using an older distribution.
