Software YDLidar-SDK

From Git repository

$ mkdir -p git

Ros2 Iron

Base

Add en_DK.UTF-8 in this list

$ sudo dpkg-reconfigure locales

Then run

$ sudo update-locale LC_ALL=en_DK.UTF-8 LANG=en_DK.UTF-8
$ export LANG=en_DK.UTF-8

Follow https://docs.ros.org/en/iron/Installation/Alternatives/Ubuntu-Development-Setup.html

Note, I got:

E: Malformed entry 1 in list file /etc/apt/sources.list.d/ros2.list (Component)
E: The list of sources could not be read.

Then I modified /etc/apt/sources.list.d/ros2.list

sudo nano /etc/apt/sources.list.d/ros2.list

by adding "bookworm" near the end of the line

deb [arch=arm64 signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu bookworm main

The bookworm came from:

$ lsb_release -sc
