Error installing PySide6 on Ubuntu

  • Hi!

    I'm trying to install Pyside6 on Ubuntu on a Conda environment using pip. I get the following error:

    File "", line 5, in <module>
    from PySide6.QtCore import Qt
    ImportError: /lib/x86_64-linux-gnu/ version `GLIBC_2.25' not found (required by /home/joel/anaconda3/lib/python3.7/site-packages/PySide6/Qt/lib/

    Any ideas why PySide6 is not installing correctly? OS version is Ubuntu 16.04.4

    Hi and welcome to devnet,

    I don't recall pip installing it's own copies of glibc.

    That said, Ubuntu 16.04 is not listed on the supported platform, the minimum is 20.04.

    See here the list of supported platforms.

  • Thank you for the prompt response!
    I have moved to CentOS8 .2 (which is supported) and I now, after resolving package dependency errors, I get a different error:

    qt.qpa.wayland: Creating a fake screen in order for Qt not to crash

    I get a window but it is not responsive (menus are empty). Any thoughts as to how to solve this issue? I'm trying to run a graphical desktop application on a VM running CentOS 8.2.

    Which desktop environment are you running ?
    From the looks of it, you have a Wayland server for the graphical rendering.

  • I believe I'm running the default which is Wayland.

    Might be related to QTBUG-98010.
