QCAD on Ubuntu 22.04.1 crashes

[asala]

PC with 6.2.0-34-generic #34~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Sep 7 13:12:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

First I installed QCAD trial version: all right, no issues.
Then I purchased the PRO version, downloaded qcad-3.28.2-pro-linux-x86_64.run, made it executable and run from a terminal window. Apparently the installation was OK. No errors

But starting it I get the splash screen, then nothing. Running ./qcad from terminal window I get
~/opt/qcad-3.28.2-pro-linux-x86_64$ ./qcad
QCAD version 3.28.2

QCAD has unexpectedly quit.

Please use the offscreen or minimal platform plugin for headless systems
(without a running X11 server):
./qcad -platform offscreen

In addition, you might have to override the default Qt style
to prevent the loading of a native desktop style (such as GTK):
./qcad -style plastique


BTW, the trial version keeps working correctly

What should I do ?

Thank you and best regards

Hi, and welcome to the QCAD forum.

Similar crash report with solution here:

I would remove the trial version first.

Please try the installer "qcad-3.28.2-pro-linux-qt5.14-x86_64.run" instead (labeled "QCAD Professional 3.28.2 for Linux Qt 5.14 64bit (Installer)" on your download page).

This version seems OK. Let me check it thoroughly
Thank you for your support

Yes, it seems the same problem with the same solution, and it works. Thank you
BTW I uninstalled the trial version but... things don't change. The solution is to use qt5 version.

Best regards
