Where is the Qt Maintenance Tool?

I've installed QtCreator in Kubuntu 15.10 through apt-get and it say my computer doesn't have the required Qt Kit and can be installed through Qt Maintenance Tool.

But I don't think I have Qt Maintenance Tool in my start menu and didn't found it in Synaptic.

Install Qt development packages qt5-default qtdeclarative5-dev through apt-get.

I found the maintenance tool binary for my installation at /opt/Qt5.7.0/MaintenanceTool on Ubuntu 14.04.

I found it by using the locate tool:

sudo apt-get install mlocate
sudo updatedb
locate -i maintenance | grep -i qt

Anyways, using the maintenance tool with the apt provided package was a rabbit hole with other problems. I ended up installing a fresh version of QtCreator from the universal linux binary install provided at qt.io installing into $HOME/Qt. Uses of that maintenance tool actually do work and I can upgrade Qt Versions easily.

Just add a Kit of your own choice in:

Tools > Options > Build & Run > Kits > (press) Add (button on the right side) > (give the Unnamed kit a name, or not, your choice) > Apply | OK

Note: The default kit, which comes pre-installed didn't work for me. So I recreated one.

You can select compiler kits, tools, platform, version of qt and anything else for your kit if you need to.
