Install ROS Noetic ubuntu20.04

Until now, melodic was used, but with the new PC, ubuntu20.04 was installed to build a ros-noetic environment.

Set up the source list

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

Set key

sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

Is the Debian Package Index up to date?


sudo apt update

Package installation

sudo apt install ros-noetic-desktop-full
sudo apt-get install python3-rosinstall

It takes more than 10 minutes. .. ..

Create a workspace immediately. .. .. But

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
catkin_make

command'catkin_make'Cannot be found. You can install it in the following ways:

sudo apt install catkin

?? ?? ?? For the time being, as instructed

sudo apt install catkin

Loading the package list...Done
Creating a dependency tree
Reading status information...Done
Some packages could not be installed. Probably possible
Did you request no situation?(I'm using an unstable distribution
If)Required packages have not been created yet or moved from Incoming
It is possible that it has not been moved.
The following information may help resolve this issue:

The following packages have unmet dependencies:
 catkin :Dependence: python3-catkin-pkg (>= 0.4.14-2)But not trying to install
E:Unable to solve the problem. I have a broken change-protected package.


Turn off the terminal once and restart

cd ~/catkin_ws
catkin_make

Build complete! I haven't put anything in it yet, but I've confirmed that/build/develop is done!
