Unable to locate package ros-rolling-navigation2 on Ubuntu 22.04

[Yongkie Wiyogo]

I try to use navigation2 with my installed ros2-rolling. Running sudo apt install ros-rolling-navigation2 returns
Unable to locate package ros-rolling-navigation2
Running sudo apt install ros-humble-navigation2 works.

Should I do extra step to install the ros-rolling-navigation2 package or it's just doesn't exist?

[Steve Macenski]

there is no rolling binary. build from source.

@SteveMacenski I follow the instruction and run these commands:

mkdir -p ~/nav2_ws/src && cd ~/nav2_ws
git clone https://github.com/ros-planning/navigation2.git  ./src/navigation2
vcs import ./src < ./src/navigation2/tools/underlay.repos
rosdep install -y --from-paths ./src  --ignore-src

The rosdep install returns these error msgs:

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
nav2_bringup: Cannot locate rosdep definition for [slam_toolbox]

Did I miss something?

[Steve Macenski]

You should also install slam toolbox, optional if you want to use the slam launch file.

Thanks! I'm new in ros2, which slam launch file did you mean exactly?
Isn't it maybe a dependency issue? So, the installation of nav2 needs slam_toolbox, and if I read the slam_toolbox, it needs to install nav2. In this case, I'm just trying to install the package, not to launch any launch file.
Or is the navigation2 package is part of the slam_toolbox?
