@Nikolay_spb
What is your $DISPLAY environment variable set to? Are you running a VM or what/how for this Mint and how do you connect to it?

I do not know what this phrase means.

In any case your issue is qt.qpa.xcb: could not connect to display :1.0. Usually the main display is 0:0. That is all I know. Someone else will understand this X display issue better than I and hopefully comment.

@Nikolay_spb Your PyQt installation has nothing to do with QtCreator, how did you install QtCreator?

Nikolay_spb

very thanks

Nikolay_spb

@eyllanesc sudo apt install qtcreator

eyllanesc

@Nikolay_spb Are you using any special environment?

Nikolay_spb

python3 -m venv env

@Nikolay_spb I think I have not let myself be understood: QtCreator is orthogonal to PyQt so please don't talk about pyqt anymore. My question is if you are using a VM, docker, etc.

Nikolay_spb

@eyllanesc no i use desktop pc and os linux mint

eyllanesc

@Nikolay_spb So it seems to me a bug in your OS, I recommend you report it. And so that you do not confuse them, do not mention anything about python that is irrelevant. In this forum little or nothing will be able to help you.

eyllanesc

@Nikolay_spb Does your OS installation have a desktop manager?

Would be nice to mention which one.
Is X server running or do you use something else (like Wayland)?
