Bug report

Required Info:

• Operating System:
  • Ubuntu 18.04.3 LTS
• Installation type:
  • apt-get

Steps to reproduce issue

I'm using osrf/ros:melodic-desktop-full Docker, image ID 41cf94b19c28 to install ros-crystal-ros-base, which includes ros-crystal-rcl-interfaces.

I'm experiencing the issue reported on #159, which was already closed.

The version that I have of ros-crystal-rcl-interfaces is 0.6.3-0bionic.20190817.173025.

According to the releases on https://github.com/ros2/rcl_interfaces/releases, version 0.7.4 was already released, but somehow apt-get only installs 0.6.3, and if you look carefully on the version details 0.6.3-0bionic.20190817.173025, it shows the date 20190817, but the version 0.7.4 was published on the 30th of May, according to the releases page aforementioned.

How can I install the latest version of ros-crystal-rcl-interfaces to solve issue #159?

The commands I used:

docker run -it osrf/ros:melodic-desktop-full /bin/bash

then

apt-get update
dpkg -l | grep rcl-interfaces
apt-get update && apt-get install -y curl gnupg2 lsb-release git
curl http://repo.ros2.org/repos.key | apt-key add -
echo "deb [arch=amd64,arm64] http://packages.ros.org/ros2/ubuntu `lsb_release -cs` main" | tee /etc/apt/sources.list.d/ros2-latest.list
apt-get update
apt-get install ros-crystal-ros-base python3-colcon-common-extensions -y
dpkg -l | grep rcl-interfaces
apt-get install --upgrade ros-crystal-rcl-interfaces

I think the most relevant outputs are:

root@f2a3fd144497:/# apt-get install --upgrade ros-crystal-rcl-interfaces

Expected behavior

When I install ros-crystal-ros-base on ROS Melodic Docker I have the version 0.7.4 of ros-crystal-rcl-interfaces

Actual behavior

The installed version is 0.6.3-0bionic.20190817.173025

According to the releases on https://github.com/ros2/rcl_interfaces/releases, version 0.7.4 was already released, but somehow apt-get only installs 0.6.3, and if you look carefully on the version details 0.6.3-0bionic.20190817.173025, it shows the date 20190817, but the version 0.7.4 was published on the 30th of May, according to the releases page aforementioned.

The latest version of rcl_interfaces released into Crystal is 0.6.3. The versions starting with 0.7.x are only released into ROS Dashing (currently 0.7.4). You can't install those on Crystal.

The problem you are facing is not addressed by a single PR. It required a new feature to be developed in #174 and then the following PR to use this for the Log message: ros2/rcl_interfaces#67.

It is unlikely that these changes will be backported to Crystal. I would recommend that you consider moving to Dashing instead in which this is resolved.

Thanks @dirk-thomas

I installed ros-dashing instead of ros-crystal as you suggested and I got the right version of rcl_interfaces. The problem described on #159 also has gone away.

I never understood very well the differences between the different ROS2 versions, but in summary, most recent versions basically have more recent versions of the individual packages, like what happened with rcl_interfaces, in addition to some packages that are removed and others that are added, right? Because the difference between ros-crystal-rcl-interfaces and ros-dashing-rcl-interfaces is basically the version of rcl_interfaces.
