I am using Qt 5.10.1 on windows 10, when I was trying to add qt repositories using the Maintenance Tool, specifically I need to add the Qt Charts module. Then it gave me this error:
Your Maintenance Tool appears to be older than 3.0.2. Please update it first to get access to new Qt packages.
Why would this happen? I am currently using the latest Qt version, and I did not find a way to update the Maintenance Tool. How can I solve this problem?
Once Qt is installed, you can use the Maintenance Tool under <install_dir> to add components and to update or remove installed components.
on Windows you can just enter "maintain" after pressing the Windows Home button, and the maintenance tool will appear as "Maintain V-Play SDK" if you are using the latest installer. If you are using the beta version, it will show up under "Maintain Qt SDK".
Download the Qt installer from its official download site at https://www.qt.io/download-qt-installer. The site should detect that your computer is running linux and recommend "Qt Online Installer for linux". Click the green "Download" button to download the installer.
I just encountered this issue.
Strangely enough, if you hit the quit button when this happens, the tool moves onto the next page, and then prompts you if you want to exit. If you cancel exiting, it then allows you to update the maintenance tool (the current version is apparently 3.0.4).
So basically, hit "quit", cancel the exiting, and it then updates itself.
