Errors starting STM32CubeIDE in MobaXterm

[Kman]

Existing STM32CubeIDE works great in Ubuntu 16.04 for STM32H747XI6. When I start it in MobaXterm in Windows laptop, I get these errors:

./stm32cubeide

SWT SessionManagerDBus: Failed to connect to org.gnome.SessionManager: Could not connect: Connection refused

SWT SessionManagerDBus: Failed to connect to org.xfce.SessionManager: Could not connect: Connection refused

IDE opens in the workspace, but I can not compile or debug the project.

[Kman]

Solution is: upgrade Ubuntu to 20.04. Now STM32CubeIDE 1.5.0 starts in Windows laptop with minor warnings, when child frames are opened:

./stm32cubeide
