[solved] Failing installing qt5 libraries (Linux mint 19.1 Cinnamon)

[Falkenkopf]

Thank you for you hints.

I couldn't solve it. These packages weren't in my standard repositories. Building from sources is something, I never tried.

I set up my whole system new (due to other problems with graphic card, that I never could solve, even with deep recherche.

Now with the actual mint version, all packages are available in the repository.
