@JacobNovitsky tried to do following:

How to upgrade to latest 6.4.2 version (or higher) ?

@JacobNovitsky Do you want the latest Qt library (6.5.2) or the latest Qt Creator (11.x)?

Your screen shot is the version details for you Ubuntu-distributed Qt Creator (6.0.2) and its the Qt run time (5.15.3) it is using. The Ubuntu-provided Qt Creator is quite old. This is not directly connected to the version, or versions, of Qt libraries you develop with.

You can get later versions of both, independent of what is in the Ubuntu packages, using the Qt Online Installer.

So far as I know:

If you have done apt install qt6-base-dev you have installed the latest available Qt6 pre-compiled for your Ubuntu, whatever version of Qt6 that might be.
If you want another version you need to use Qt online installer to fetch it. And I think you will get sources and have to compile yourself.

@JonB If im using wget https://download.qt.io/official_releases/qt/6.4/6.4.0/single/qt-everywhere-src-6.4.0.tar.xz, how to change download mirror to berkley?

@JonB said in how to install Qt6 (latest) for ubuntu 22 (Jammy Fish):

If you want another version you need to use Qt online installer to fetch it.

Or, another option, is to use Another Qt installer (aqt), like:

aqt install-qt linux desktop 6.6.0 gcc_64

Tip: I find this webpage very handy for generating the right aqt command to install the version and modules I want (I use extensively in CI environments) - that's how I generated the example command above.

Cheers.
