My favourite CD ripper Audex more doesn't seem to be in the repositories for 20.04LTS, and installing the last available version in 16.04 LTS doesn't work because kde-runtime isn't available. Is it available by any other means? thanks!
The source code on github has mentions of Qt5 and KF5, so I was preliminary wrong about its obsolescence.
We can compile and install it:
sudo apt-get install git build-essential cmake extra-cmake-modules \ qt5-default dh-buildinfo docbook2x libcdparanoia-dev pkg-kde-tools \ qtscript5-dev libqt5x11extras5-dev libkf5plasma-dev \ libkf5completion-dev libkf5crash-dev libkf5iconthemes-dev \ libkf5kcmutils-dev libkf5kio-dev libkf5cddb-dev cd ~/Downloads git clone https://github.com/KDE/audex.git cd audex cmake . make -j3 sudo make install
And then use it as usual.
I've been using N0rbert's instructions for a while, but now qt5-default is deprecated and has no installation candidate. So instead of qt5-default, add these packages:
apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools libkf5textwidgets*
The make process throws a lot of warnings about deprecated declarations in the code, but it still compiles and works.
