Unsolved Installing Qt 5 on Debian
I want to install Qt 5 on my brand new Debian 10 but I'm a bit confused. There is an online linux installer on this site and there are many qt5* packages available on the Debian repository and they are a lot. What is the best way to install Qt 5 on Debian? I guess that the best one is to use the online installer but am afraid that it could affect my current installation (KDE).
These are the available packages for installation:
(note that already most libqt5* packages are already installed by default required by KDE)

That's debian stable? Do you intend to develop with Qt?
If you only want the client binaries, then stick to what the repo gives you. If you want to develop with Qt, then you'd probably want the online installer from the QtC website. The stable flavor debian comes with somewhat outdated versions of Qt. If you decide to stick to what the repo has, then you need the libqt5*-dev packages to pull the headers for development.
To add to @kshegunov, unless you try to mess with your system installed libraries, you will not have troubles. The online installer proposes by default either your home folder or /opt which is outside what your system uses by default for loading system libraries.
@kshegunov I am planning to develop... Then it will be better to use the online installer... Does it setup the system to the new (online) Qt paths to binaries and libraries or I must do it manually? Thanks!
No, your system is left untouched. If you use Qt Creator, that handling will be done for you.
If you want to develop in a terminal, use the full path to the tools.
@SGaist I will try the online installer then... Does it fix the system paths to the new Qt binaries and libraries or just downloads the files and I must set them manually? Thanks!

None of the above. The installer doesn't touch system paths, and it really shouldn't. As @SGaist said it's up to
qmaketo set it up for you, so using the correct
qmakebinary, assumedly configured in QtCreator' kits is enough to get you started.
