Suposing that catkin was automatically installed with noetic, when I used catkin_make, the command was not found. I tried to install catkin but I received :
The following packages have unset dependencies:
catkin: Depends: python3-catkin-pkg (>= 0.4.14-2)but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
The package python3-catkin-pkg (0.4.24-100) is really installed.
What can I do?

Pls make sure not to forget to source.

Comment by MiguelMTS on 2022-01-24:
I did not forget to source.
I also had used the same repositories as in question 3417.and that was the result.
Comment by AlessioParmeggiani on 2022-01-25:
Have you tried installing python catkin tools?
sudo apt install python3-catkin-tools
Comment by MiguelMTS on 2022-01-25:
Yes, I did too, and finally arrived to the impossibility aforementioned.
I have repeated the process from the beginning several times and in different ways and always gat the same final result.
Comment by osilva on 2022-01-25:
It could be a Kubuntu issue not necessarily ROS. Ubuntu is the recommended OS
Comment by gvdhoorn on 2022-01-25:
What is the output of:
lsb_release -adpkg -l | grep catkin- after
sourceing:which catkin_make
And what does:
I did not forget to source
mean exactly?
Unless you've setup to auto-source (via your .bashrc fi), you'll have to source in every terminal manually. A single time won't work for future terminals.
Edit, just noticed:
I tried to install catkin [..]
how? Which command did you use, exactly?
Note that catkin is not the same package as python3-catkin-pkg.
And the latter is not the package which provides the catkin_make command. That would be ros-noetic-catkin. Are you perhaps mixing in wiki/UpstreamPackages?
Comment by MiguelMTS on 2022-01-25:
Yes, I included source via .bashrc.
I used ros-noetic-catkin
The result for dpkg is:
ii python3-catkin 0.8.0-1ubuntu2 all
ii python3-catkin-pkg 0.4.16-1 all

Sorry.
1.-Before installing noetic
From lsb_release -a, I receive:
NoLSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
But now the situation has changed
I am installing on RaspberryPi 4.
Ubuntu 20.04.3 Server LTS (desktop versión is not available) With the apt update after the curl command, there appears an error when getting
http://packages.ros.org/ros/ubuntu foval InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654
Then I tried with gpg --fetch-keys https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc
That imported the key for 'Open Robotics <[email protected]>"
But again Received the same error after apt update.:

this is the first time you mention this.
In the future, please provide pertinent details like this, as otherwise it will be very difficult for people here to help you.
there appears an error when getting
http://packages.ros.org/ros/ubuntu foval InRelease
is foval a typo? Or did you copy-paste it?
The correct codename for your distribution would be focal (note: c, not v).
Comment by MiguelMTS on 2022-01-26:
Sorry. It was a typo error in the comment. Of course the message says focal, not foval.
And sorry again, I missed to mention the Raspberry in my first entry.
