Here’s my error. I’m trying to run make px4_sitl gz_x500 which used to work last night. I am running Ubuntu 24.04 and Gazebo Harmonic. Now it says Gazebo gz please install-gz garden. I think the error also might arise from gz_bridge. I’m not sure because I was also trying to install mavlink last night. Any ideas how to fix this error?

I had the same problem before and solved it by following steps:

$ which gz
> /opt/ros/jazzy/opt/gz_tools_vendor/bin/gz

It turned out to be the wrong binary.

$ dpkg -l | grep gz

It’s ros-jazzy-gz-tools-vendor.

The problem occurred because I had previously installed rqt using apt install ros-${ROS_DISTRO}-rqt* .

Let’s fix it.

$ sudo apt remove ros-jazzy-gz-tools-vendor

And reinstall gz.

$ ./Tools/setup/ubuntu.sh

Check

$ gz
> I cannot find any available 'gz' command:
>         * Did you install any Gazebo library?
>         * Did you set the GZ_CONFIG_PATH environment variable?
>             E.g.: export GZ_CONFIG_PATH=$HOME/local/share/gz

Still has some problem.

$ echo $GZ_CONFIG_PATH
> /opt/ros/jazzy/opt/sdformat_vendor/share/gz

I don’t know which package set the GZ_CONFIG_PATH value.

But we can make it point to the correct path.

$ export GZ_CONFIG_PATH=/usr/share/gz/

Let’s Check again

$ gz sim --version

$ make px4_sitl gz_x500_depth

Solved!
