 Many distributions, in particular Debian, Ubuntu (especially LTS releases), and their derivatives don't provide up-to-date Qt packages in their repositories or are very slow in updating them.
 In such cases, you must get them from somewhere else, such as the official installer from the [Qt website](https://www.qt.io/download-qt-installer) (unfortunately, this method requires the creation of an account, but you can just use a throwaway email), or a PPA you trust in the case of Ubuntu and other distributions that support that installation method.
 
 For Debian and Ubuntu versions that include sufficiently up-to-date Qt packages, you can just install the following packages from the official repositories:
 
 ```bash
-sudo apt install --no-install-recommends qtbase5-dev qttools5-dev libqt5svg5-dev
+sudo apt install --no-install-recommends qt6-base-dev qt6-base-private-dev qt6-tools-dev qt6-svg-dev
 ```

 The install step will install libtorrent to the chosen prefix (`/usr/local`, in this case), and generate an `install_manifest.txt` file in the build folder that can later be used to uninstall all installed files with `sudo xargs rm < install_manifest.txt`.
