Problem with installation and reading Stm32

[milad]

Hello,
I have recently installed STM in Linux, but after installation, this file cannot be displayed
As you can see in the picture.

Does anyone have a solution?

Make sure that you have a supported Linux version. The list of supported versions is in the CubeIDE Installation guide.   From the background on your screenshot this is some Ubuntu variant but can't tell for sure.
