Pyqt4 on Ubuntu 20.04 install

  • 772

I use a chess application called "Lucaschess" and it needs PyQt4 module to work. Is it possible to install Pyqt4 on Ubuntu 20.04? I understand that Ubuntu no longer supports this package but is there anyway which I can work around?

    The Qt4 packages can still be obtained from third party PPA:

    sudo add-apt-repository ppa:rock-core/qt4
sudo apt-get update

    Then you have to download python-qt4 binding from previous Ubuntu 18.04 LTS release manually:

    cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/universe/q/qt-assistant-compat/libqtassistantclient4_4.6.3-7build1_amd64.deb
sudo apt-get install ./libqtassistantclient4_4.6.3-7build1_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/python-qt4/python-qt4_4.12.1+dfsg-2_amd64.deb
sudo apt-get install ./python-qt4_4.12.1+dfsg-2_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/python-pyaudio/python-pyaudio_0.2.11-1build2_amd64.deb
sudo apt-get install ./python-pyaudio_0.2.11-1build2_amd64.deb

    As the result the Python2-Qt4 binding will be installed. Then you know what to do.

    Also note that there is fresh version of lucaschess here with Qt5 as dependency.
