I want to install the package rosdep install --from-paths src --ignore-src -r -y but the program gives an error rosbot_navigation: Cannot locate rosdep definition for [map_server].I tried to fix it but it didn’t work.
i use ROS Melotic and unbutu 18.02
ROS Melodic is EoL, so I suggest switching to a newer distro at the first opportunity to reduce the chances of future bugs. The quickest solution to your problem should be to manually install the packages with:
apt install ros-melodic-map-server
In the case of errors with other packages, proceed in the same way:
apt install ros-melodic-<name-of-package>
Please tell me if it works.
i work for me,thanks you so much
