Ubuntu 20.04 中的 Pyqt4

Question

How to install Pyqt4 in ubuntu 20.04
I have already tried all the commands:

sudo apt-get install python-qt4
sudo apt-get install libqt4-dev
sudo apt-get install pyqt4-dev-tools
sudo apt-get install pyqt4.qsci-dev
sudo apt install python3-pyqt4

But it kept on saying module has no installation candidate although pyqt5 is running smoothly but code is too long for changing it to pyqt5

Answer 1

I am actually stucked to install something which required PyQt4 on Ubuntu 20.04, the only solution I've got is to install Qt4 Library that way

1. sudo add-apt-repository ppa:rock-core/qt4

2. sudo apt update

3. sudo apt install libqt4-declarative libqt4* libqtcore4 libqtgui4 libqtwebkit4 qt4*

Hope that will help you a little bit more

That PPA is also missing the mysql plugin for QT4. You can rebuild it from scratch (with apt source + debuild) by modifying the apt source per these instructions: Qt 5.10.0 MySQL drivers fails to compile on Fedora 27
