Hey there! We’re having some issues getting [Demo #1: Mapping and Navigation](https://docs.hello-robot.com/0.3/getting_started/demos_mapping_and_navigation/) working properly. Upon running `ros2 launch stretch_nav2 offline_mapping.launch.py` the RViz window appears, however the map frame doesn’t exist and there are no messages being sent on any of the `/map` topics. Here is a picture of the RViz window after running the launch file.

 ![Screenshot from 2025-07-14 12-20-58](https://canada1.discourse-cdn.com/flex030/uploads/hello_robot2/original/2X/e/ee389f595682797a1d6f479a587238251371b6bd.png)

We think this could be fixed by running `stretch_install`, however that fails on line 69  
`rosdep install --rosdistro=humble -iy --skip-keys="librealsense2 realsense2_camera" --from-paths src &>> $REDIRECT_LOGFILE` in `stretch_install/factory/22.04/stretch_create_ament_workspace.sh`. In the log files it appears to look for the 2024 version of the dependencies instead of 2025. We could manually install the 2025 versions of the dependencies, however we wanted to double check this is the right course of action before-hand. Thanks!

Hi @cscott, thank you for the detailed breakdown. Would you copy in or link to the log files? Specifically, the one that matches the stretch\_create\_ament\_workspace script would be helpful.

Once we get the workspace set up again, we can look into the issue with Demo 1.

We figured that updating the packages that couldn’t be found to the newest versions listed on OSL would fix the issue, but aren’t sure if those are the right ones.

Yes, I think that would help, but you don’t have to do it manually. The above error makes it seem like `sudo apt update` would update Apt’s cache. I believe you’d then be able to use the workspace creation script without issue. If this proves true, I can add `sudo apt update` to the script. If not, I found a [stack overflow issue](https://robotics.stackexchange.com/questions/104189/failed-to-fetch-http-packages-ros-org-ros2-404-not-found) that suggests `sudo rm /var/lib/apt/lists/*` to delete the cache, followed by `sudo apt update` to grab a new cache.

Hi, @bshah I am working with @cscott. I was able to get us past the apt update issue (below) and create the workspace, but building is a problem due to the setuptools version. I can’t attach files here (I get an error new users can’t attach files) which makes formatting of the debugging steps messy. Everywhere I refer to an colcon\_build\_output\*.txt, I will format as its own message later. I also get a notification that new users can only link 2 links in a post, so for links I add a space between http or https and : to break them, as the links are automatically generated by the post formatter. It may be helpful for your forum to increase that limit, especially as many error messages include links. I had to combine colcon\_build\_output1 and 2 into the same reply as “An error occurred: We’re sorry, but new users are temporarily limited to 3 replies in the same topic.”

Thank you,  
Taylor

```

Since this is still an issue, I cd into /etc/apt/sources.list.d. There I do

```auto
hello-robot@stretch-se3-3096:/etc/apt/sources.list.d$ ls
github-cli.list librealsense.list nodesource.list ros2.list

```

Since the deb with an issue is nodesource, I know to look into nodesource.list. So, when I vi nodesource.list I see deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https ://deb.nodesource.com/node\_21.x nodistro main. deb allows an arch specification, so to find what I should specify I do:

```auto
hello-robot@stretch-se3-3096:/etc/apt/sources.list.d$ dpkg --print-foreign-architectures
i386
hello-robot@stretch-se3-3096:/etc/apt/sources.list.d$ dpkg --print-architecture 
amd64

```

This confirms to me the issue is deb is getting the i386 version and we need the amd64 version. So I add “arch=amd64” to the deb specifications, so nodesource.list now has deb [signed-by=/etc/apt/keyrings/nodesource.gpg, arch=amd64] https ://deb.nodesource.com/node\_21.x nodistro main. **note: there is a space there that I needed to added to let me post due to the link limit, there should not be a space between the https and : above** Now the update is successful!

Unfortunately this doesn’t help a ton because when I run colcon build in ament\_ws we get the attached errors in colcon\_build\_output.txt. They’re all seemingly the same:  
CERROR: setuptools==59.6.0 is used in combination with setuptools-scm\>=8.x  
Your build configuration is incomplete and previously worked by accident!  
setuptools-scm requires setuptools\>=61  
This is a git issue: https ://github.com/pypa/setuptools-scm/issues/1112. One of the solutions is upgrading pip since our setuptools versions should work together. Our pip was a bit old, so I upgraded it to 25.0.1 based on this commit https ://github.com/mozilla/translations/commit/ab61ad90e0b3511ca1417cf448dc6e3faf80c732. **note: I needed to add spaces in the above links to let me post due to the link limit, there should not be a space between the https and : above**

Still has the same issue, so I update pip to 25.1.1 which is the newest version and update setuptools to the newest version. setuptools-scm is already up to date.

Now when I run colcon build I get the errors in colcon\_build\_output2.txt. I update setup tools to the minimum version needed for setuptools-scm, 61.0.0

`hello-robot@stretch-se3-3096:~/ament_ws$ pip install setuptools==61.0.0`

Unfortunately we get more errors, in colcon\_build\_output3.txt. For stretch\_funmap ast.literal\_eval error due to the python version and the code (colcon\_ros/package\_augmentation/ros\_ament\_python.py) being out of sync. I look and some people have had similar issues as I have with everything above ([FUNMAP colcon build error · Issue #203 · hello-robot/stretch\_ros2 · GitHub](https://github.com/hello-robot/stretch_ros2/issues/203)). I downgraded pip back to 24.3.1 since the upgrade previously wasn’t necessary. I then removed requires-python = “\>=3.10” from src/stretch\_ros2/stretch\_funmap/pyproject.toml per issue 203 above, which fixed stretch\_funmap but everything else still shows a git issue. See colcon\_build\_output3.txt for the full log, but a snippet is below.

```

This issue is most likely related to setuptools ([https://robotics.stackexchange.com/questions/104326/colcon-build-on-ros2-humble-outputs-listing-git-files-failed-pretending-there](https://robotics.stackexchange.com/questions/104326/colcon-build-on-ros2-humble-outputs-listing-git-files-failed-pretending-there)).

Hi @tberg1234, thank you for the details. First, unfortunately Discourse doesn’t have a setting to allow new users to upload files. I’ve bumped you to Trust Level 1, so you shouldn’t see those errors anymore.

I think your original issue was

```auto
Err:5 http ://packages.ros.org/ros2/ubuntu jammy InRelease
  The following signatures were invalid: EXPKEYSIG F42ED6FBAB17C654 Open Robotics info@osrfoundation .org

```

and it looks like you’ve fixed it using `sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg`.

Then, it looks like you solved the node warning too by adding “arch=amd64”. I’ve opened [a PR to fix this in our install scripts](https://github.com/hello-robot/stretch_install/pull/95).

Then, it looks like you set up a ROS workspace without issue:

```auto
#############################################
DONE! ROS WORKSPACE SET UP SUCCESSFULLY.
#############################################

```

Internally, this script has used `colcon build --symlink-install`, so if you’re editing existing Python nodes, you don’t need to build the workspace.

In “colcon\_build\_output1.txt”, you actually have no errors. Although setuptools prints out errors loudly and there are warnings too, none of these affect the actual compilation. At the end, all 34 packages build successfully:

```auto
Summary: 34 packages finished [29.6s]

```

In “colcon\_build\_output2.txt”, you run into build errors because you updated pip to a newer version. Unfortunately, ROS requires an older version of pip when using cython extensions (as Stretch FUNMAP does). This is why we [downgrade pip inside the workspace script](https://github.com/hello-robot/stretch_install/blob/e9b3348a76294840778e86d1cbd27b1e81789f94/factory/22.04/stretch_create_ament_workspace.sh#L106-L107).

In “colcon\_build\_output3.txt”, you’ve removed Stretch FUNMAP from the build list, so only 33 packages build successfully:

```auto
Summary: 33 packages finished [22.1s]

```

If you rerun the `stretch_create_ament_workspace.sh` script, you should get output similar to your “colcon\_build\_output1.txt” file. At that point, you should be all set to begin development.

Hope this helps! Let me know if you have any questions.

Hello @cscott,

I faced a similar problem when I started with [Demo 1: Mapping and Navigation](https://docs.hello-robot.com/0.3/getting_started/demos_mapping_and_navigation/) on SE3. In my case, upon running `ros2 launch stretch_nav2 offline_mapping.launch.py`, I was getting a similar error in RViz: **Frame [map] does not exist**.

When I looked at the terminal output, I noticed the following message:

```auto
[stretch_driver-3] Another process is already using Stretch. Try running "stretch_free_robot_process.py"
[stretch_driver-3] [FATAL] [1753876169.429881896] [stretch_driver]: Robot startup failed.

```

By default, stretch is configured to start the **gamepad teleoperation demo** in the background on startup. So, here’s what I did:

1. Freed up the robot process by running (Disconnected gamepad teleoperation ):  
`stretch_free_robot_process.py`
2. Then launched the mapping demo again:  
`ros2 launch stretch_nav2 offline_mapping.launch.py`

After doing this, it worked perfectly, the map loaded in RViz without any errors.

Hope this helps!
