In ubuntu20.04 qt5-default was the package name. So I tried the same and qt6-default in 22.04.

Then I tried apt-cache search qt which revealed (among many others): qt6-base-dev and qt5-base-dev.

I am unsure whether the new qt{version}-base-dev is the old qt5-default. If not: What is?

    Thanks for asking, I needed this for Linux kernel 5.4 compilation.

  • Instead of Qt6 I went with Qt5 as it was having one header installation error as that header got deprecated in the Qt6

Reset to default

You need to install packages:

sudo apt install -y qtcreator qtbase5-dev qt5-qmake cmake

And you need to manually change the Qt version: screenshot how to manually change Qt version

Then you need to manually change Qt version in the Kits tab: screenshot on the Kits tab

    That -does- work to install qtcreator (and especially the proper kit stuff) onto raspberry pi (regular 32 bit os). That helped me a looot - thanks!

    Is there any documentation page for this?

    This sort of OVER-answers the question. What about for a "client" machine which only needs the Qt libraries to run programs? qt-default used to take care of that. What now? qtchooser doesn't install any libraries. qt5-base no longer exists either.

    Note that in Ubuntu 22.10 qtcreator's dependencies are all from Qt6 (see apt-cache depends qtcreator | grep qt6). qtbase5-dev is still there though (and automatically installs qt5-cmake), so just sudo apt-get install qtbase5-dev is sufficient for basic Qt5.

Starting with Ubuntu 22.04, you can use qt6-base, qt6-base-dev or qt6-tools-dev

Why don't you install it with their online installer.

Once downloaded, chmod +x qt-unified-linux-<arch>-<version>-online.run then ./qt-unified-linux-<arch>-<version>-online.run

  • I try to use the package manager whenever I am able, but you are right given my question.

    @Natan I tried the same thing. Maybe it'll get there in the future since 22.04 is relatively new.

  • Unfortunately, the online installer does not run on arm64 architecture.

  • @Dragos You can also build from source if you are unable to use the installer.

    this is a good answer and will get you the latest qt6.2+ BUT if you want to use the qt that came with your distro (especially if you use Kubuntu - which i guess you don't) then sudo apt install answer is the way to go if you want to distribute .deb files on kubuntu. which i guess you don't :)

For all who just want to install vulkan-sdk on Ubuntu 22.04 like I wanted, getting the error

The following packages have unmet dependencies:
 vulkancapsviewer : Depends: qt5-default but it is not installable

These instructions helped in my case: https://vulkan.lunarg.com/doc/sdk/1.3.236.0/linux/getting_started_ubuntu.html

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list http://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
sudo apt update
sudo apt install vulkan-sdk

    Why giving information about the vulkan SDK since the topic is to install Qt ?
