https://gazebosim.org/docs is the best source of documentation for installing Gazebo. If you want to use ROS, there's a whole section there that describes the steps.
You said you need to install gazebo_ros, but ros-humble-ros-gz is the equivalent of gazebo_ros (which is for Gazebo-classic) for the new Gazebo. If you already have ros-humble-ros-gz installed, you just need to install Gazebo Fortress

I'll admit being confused, I thought sudo apt-get install ros-humble-ros-gz actually installed Gazebo. From the doc paragraph:
The following command will install the correct version of Gazebo and ros_gz for your ROS installation on a Linux system.
I can open Gazebo by gz sim empty.sdf, but get package 'gazebo_ros' not found when running a launch file intended to spawn a robot in Gazebo.

Ah, my mistake, it looks like ros-humble-ros-gz indirectly depends on libignition-gazebo6, so yes, it does install it. If you have a launch file that is looking for gazebo_ros, that launch file is probably meant to be used with Gazebo-classic. It'll need to be updated to work with the new Gazebo.

cool, thanks. Do you have any links to documentation how to replace gazebo_ros references with new Gazebo?
Comment by Simple Simpson on 2023-06-22:
Reading the docs, gazebo_ros is still a package name, right?

gazebo_ros is still a package name, but it's meant to work with Gazebo classic. You'll want to use ros_gz with the new Gazebo. Here's a repo with examples. This video should also help
