I encountered these two issues on Neon GNU/Linux with KDE Plasma 5.10.3 on Qt Creator 4.3.0 & Qt Framework 5.9. When I installed Creator from Neon repo (not Ubuntu repo), it shows no examples at all and also it failed to create new Qt Widget project saying “No Valid Kits Found”. I solved these issues by simple workarounds below:
To Solve “No Examples” Issue
This problem arises because merely installing Creator doesn’t install the examples files themselves. So, install them by command line:
sudo apt-get install qtbase5-examples qtbase5-doc-html
To Solve “No Kits” Issue
This solved by installing qt5-default package:
sudo apt-get install qt5-default
and restarting Creator should give you both the Examples and ability to create new projects.
Result
If you performed both workarounds above, you should see Creator shows examples now:
and it can make new project (Qt Widget) now:
