changes from foxy to humble in chapter 1:

set Apt repositories:

sudo apt update && sudo apt install curl
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

sudo apt update

ROS2 available software

apt-cache search ros-humble

Install ROS2 from binaries

sudo apt update

Activate ROS2

source /opt/ros/humble/setup.bash

echo "source /opt/ros/humble/setup.bash" >> /.bashrc

Create and fill

cd ~
mkdir -p bookros2_ws/src
cd bookros2_ws/src
git clone https://github.com/fmrico/book_ros2.git
vcs import . < book_ros2/third_parties.repos

---

while importing third-party repos using vcs if you run into the error:

Command 'vcs' not found

we have to install vcs using the below command:

sudo apt install python3-vcstool

---

install dependencies:

sudo rosdep init
rosdep update

cd ~/bookros2_ws
rosdep install --from-paths src --ignore-src -r -y

---

while installing dependencies if you run into the error,

rosdep command is not found.

then run the following command:

sudo apt install python3-bloom python3-rosdep -y

then initialize rosdep

sudo rosdep init
rosdep update

---

if you run into an error while running rosdep init: try:

sudo apt update && sudo apt upgrade

if this does not solve then do the below steps:

• open hosts file:

  sudo gedit /etc/hosts

• add this line to the end of the file:

  151.101.84.133 raw.githubusercontent.com

• save and close, then run:

  sudo rosdep init
  rosdep update

  ---

posting changes as an issue as asked in the LinkedIn post.

Hi @varunvenna !! Maybe I could have explained myself better. My request was for corrections and typos. I already had updated to Humble. In any case, thank you for your effort. I will include you as a reviewer in the book.
