Hello Rafał,
I get all the same messages as you, however there is also some override happening for the DDS client, I don’t know whether it is an issue:
zarzadca@admin:~ $ sudo snap logs rosbot

Regarding ROS running - to connect to the RPi 5 I use Tiger VNC viewer that can stream display from my RPi to the laptop, however you can say they are connected via the Wi-Fi that my laptop is streaming using hotspot to the RPi. I’m not using ROS on my laptop. I checked any other Docker containers with ROS on my RPi, however they are not running.
I believe this check is ok:
zarzadca@admin:~ $ sudo snap get rosbot ros
Key Value
ros.domain-id 0
ros.localhost-only
ros.namespace
ros.transport udp
zarzadca@admin:~ $ sudo snap get husarion-webui ros
Key Value
ros.domain-id 0
ros.localhost-only
ros.namespace
ros.transport udp
zarzadca@admin:~ $ sudo snap get husarion-rplidar ros
Key Value
ros.domain-id 0
ros.localhost-only
ros.namespace
ros.transport udp
This also looks fine:
zarzadca@admin:~ $ snap list

This check was a little bit concerning:
zarzadca@admin:~ $ sudo snap get <snap_name> ros.transport
bash: snap_name: No such file or directory
zarzadca@admin:~ $ sudo snap get ros.transport
bash: rosbot: No such file or directory
zarzadca@admin:~ $ sudo snap get ros.transport
bash: husarion-rplidar: No such file or directory
When starting the just start-navigation I would always get this prompt: sudo: husarion-webui.start: command not found. Then I remembered that in order to perform sudo rosbot.stop or sudo rosbot.start I had to add /snap/bin for it to work. I went with this clue and changed the just file to: sudo /snap/bin/husarion-webui.start sudo /snap/bin/husarion-webui.stop. Then just start-navigation worked. Do you think it’s a problem with my environment?
Also when using the web ui I was getting this prompt that the map could not be saved as on the screen below:
Teleop and goal setting was working correctly - do you have any ideas/recomendations?
Big thanks,
Mateusz Norek
