Ros Instalation Error - Unable to locate package ros-galactic-desktop

edit

System: Ubunut 22.04 LTS, distribution Ros2 Galactic

Issue:During the initial installation process ( I follow this tutorial https://docs.ros.org/en/galactic/Inst...), system fails to locate package ros-galactic-desktop after command "sudo apt install ros-galactic-desktop".

cmd:

apt update
apt install -y locales

locale-gen en_US en_US.UTF-8
update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
apt update 
apt install -y curl gnupg2 lsb-release
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 $(source /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null
apt update
apt install -y ros-galactic-desktop
apt install -y python3-colcon-common-extensions
