[ozitoune]

Describe the bug

I just make a fresh install off ubuntu serveur 22.04 on a raspbery pi 4. I have installed and sourced px4 msg by dowloading it then colcon, no problem... I have installed uxrece by snap, and its ok , i see the px4 topics, but i have a problem with /fmu/out/vehicle_local_position and /fmu/out/vehicle_air_data... I can open /fmu/out/vehicle_odometry, /fmu/out/vehicle_attitude, and others... buen impossible to echo vehicle_local_position... I have used the official documenttaion ... I can see and echo this topics on another computer , or on my old ubuntu desktop install on my raspery

Here is a terminal output from a note that read different px4 topics :

`>>> [rcutils|error_handling.c:108] rcutils_set_error_state() This error state is being overwritten:

To Reproduce

Install ubuntu server 22.04 Install uxrce agent by snap downloads px4_msgs from git and build it with colcon. start the agent List ros topics , ty to echo /fmu/out/vehicle_local_position... Impossible to echo thios topic and others.

Expected behavior

normally i can echo all topics, but now some are present and other no...

This happen only on a fresh install on my raspbery pi 4 with ubuntu 22.04 server, i can echoo all topics with another computer

Did you solve this? I have the same issue.

Yes , it was a mistake from me, you need to compile the correct px4_msgs for your version , if you are on the stable firmware you have to change the branch of px4_msgs and use the 1.14 for the compilation
