This means that the converted deb package ends up having something which duplicates a file already in our base system. So, it can’t easily be installed. It might be possible to force it, but it might break something. What is the package?
Meson didn’t found CMake so I installed it, but meson also don’t found dependency alsa. How can I install alsa? I thought alsa is installed on my PC. I use it with jack when I using Ardour
Note that to compile software from source, you need to install the development package of the dependencies also. So, look for the -devel packages, so you probably need alsa-lib-devel etc.
