    instructions do not work for my version of QT Create, and once i did find preference->kit->kit, nothing was listed under auto-detected nor manual

      That sounds very strange.

      What do you see when you try Step #2 in the instructions?

          This is meaningless. It's the Qt version which was used to build your QtCreator version.

          How are your build folders named? In some case they are named by default like:
          build_<Projectname>_<QtX_X_X>_<Compiler>_<Architecture>

          There you also can find out what Qt version you are using

              Qt 5.15.3 in PATH (qt5) /usr/lib/qt5/bin/qmake

                  @micha_eleric If you are on Ubuntu 22.04 (a guess on my part), have not installed a Qt version separately from that installed by Ubuntu, and everything is up-to-date then you are using Qt 5.15.3.

                  Open a terminal and type qmake -v
