Lucaschess not running after upgrading to ubuntu 20.04 about lucaschess

[xaizek]

Those are warnings. The code isn't entirely correct, but will probably work.

Emm. Let me check

See if there are any errors

I am not able to run. Did i miss any dependency like Qt4, if yes please let me know the commands for installing them, as qt5 only seems to be available.

Thanks a lot.

Ubuntu 20.04 dropped support for Qt4. Packages from older releases might work or you can build it yourself (in both cases you also need PyQt and maybe some other old versions), look for articles on using Qt4 in Ubuntu 20.04.

You can also try https://github.com/lukasmonk/lucaschessR (not sure it works on Linux yet). Or use Windows version via Wine.

[Arunachala-Ramana]

Yeah will try searching and get back.

Emm. Installed Pyqt but now error shows up as no module called pyaudio. I did install python3-pyaudio.

python3-pyaudio is already the newest version (0.2.11-1.1build1).

Anything i did wrong?

[xaizek]

python3-pyaudio

LucasChess uses python2.

[Arunachala-Ramana]

Emm. So what should i do now to rectify? I am not aware

[Arunachala-Ramana]

Got it working. Posted this question here: https://askubuntu.com/questions/1265294/pyqt4-on-ubuntu-20-04-install and some people were very kind to help 👍 Thanks to you as well for the help.
