rmw_cyclonedds_cpp: Cannot locate rosdep definition for [iceoryx_binding_c] about rmw_cyclonedds

[eboasson]

Dashing was a very long time ago, I'm pretty sure iceoryx_binding_c didn't exist at the time and there definitely was no Cyclone+Iceoryx integration back then: it only became official in Galactic, and so I think Galactic would be the first distribution to have a rosdep definition for iceoryx_binding_c.

Why in Dashing rosdep would try to be solve some sort of a dependency on iceoryx_binding_c is a mystery to me, too. The package.xml file for Dashing/Eloquent doesn't mention anything Iceoryx.

I try to install ros2 by this step

But I'm stuck on "installing the missing dependencies".

Yeah, dashing is way out-of-date and not supported anymore. I'll suggest trying with a newer distribution; Humble is the latest, and the installation instructions for it are at https://docs.ros.org/en/humble/Installation/Ubuntu-Install-Debians.html
