Install issues using Debian 12

[Whosondephone]

following docs/INSTALLATION.md to install on Debian 10 do not work on Debian 12. I'm sorry I'm a complete n00b and am not familiar with the commands.

george@debian:~/tsMuxer$ wget -qO - https://download.opensuse.org/repositories/home:/justdan96/Debian_debbuild_10/Release.key | sudo apt-key add - echo "deb https://download.opensuse.org/repositories/home:/justdan96/Debian_debbuild_10 ./" | sudo tee -a /etc/apt/sources.list > /dev/null Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). gpg: no valid OpenPGP data found.

running the tsMuxerGUI from tsMuxeR_2.6.11.tar.gz archive yealds this:

/home/george/tsMuxer/tsMuxerGUI: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

I'd have to check if the OpenSUSE Build Service is still working and producing builds for newer distros.
