I have been following the guides at Using ros1_bridge with upstream ROS on Ubuntu 22.04 and Ubuntu (source) to build ROS2 on Ubuntu 22.04 Jammy. I've tried this for Iron and Humble.

When I try for example:

rosdep install --from-paths src --ignore-src -y --skip-keys "fastcdr rti-connext-dds-6.0.1 urdfdom_headers" --os=ubuntu:jammy --rosdistro humble

it fails with:

E: Unable to locate package python3-catkin-pkg-modules
ERROR: the following rosdeps failed to install
  apt: command [sudo -H apt-get install -y python3-catkin-pkg-modules] failed

I've looked on https://index.ros.org/d/python3-catkin-pkg-modules/ and there is nothing there for Jammy.


I might be jumping the gun but rosdep install now fails for a different reason:

The following NEW packages will be installed

  • $\begingroup$ Are you using the ros apt repositories- does grep packages.ros /etc/apt/sources.list.d/* show anything? $\endgroup$ Dec 9, 2023 at 15:15
  • $\begingroup$ grep packages.ros /etc/apt/sources.list.d/* gives deb [arch=amd64 signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu jammy main @LucasWalter $\endgroup$

  • $\begingroup$ You'll need to disable those, add a # to the start of the deb lines referencing packages.ros.org or delete /etc/apt/sources.list.d/ros2.list or similar entirely and run sudo apt update after. Then follow the docs.ros.org/en/iron/How-To-Guides/… instructions (don't follow the 'Installing ROS 2 from Source' link above that section) $\endgroup$ Dec 11, 2023 at 14:00
  • $\begingroup$ You do need to follow the vcs import steps from docs.ros.org/en/iron/Installation/Alternatives/… and colcon build it (but don't do the rosdep steps) $\endgroup$ Dec 11, 2023 at 14:06

Ran into the same problem here, following the same instructions. Solution was to pip install the packages that failed to install via apt (e.g. pip install -U catkin-pkg-modules).Next, added the failing apt install to --skip-keys. So, my working rosdep command eventually looked like this:

rosdep install --from-paths src --ignore-src -y --skip-keys "fastcdr rti-connext-dds-6.0.1 urdfdom_headers ignition-cmake2 ignition-math6 python3-catkin-pkg-modules python3-rosdistro-modules python3-vcstool" --rosdistro humble

Still working on getting ROS2 built, but this got me a step further.
