Error installing Docker

Did you follow this:
https://docs.docker.com/engine/install/ubuntu/

Yes the package is from the same place.
Install Docker Engine on Ubuntu → installation steps. → Docker Desktop for Linux. → Supported platforms → DEB package . These .deb is what I tried to install.

Why don't you just try following https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository ?

If you cannot follow that, what is the full error message that you receive for the other installation method?

In the repository way there is a error on line five and if carry on with other commands it seems
they do nothing.

The following commands looks to me they do nothing and on the end there is sudo apt-get update
which shows there are no reference to Dock.

The repo is there. Just needs the line in the sources file tweaking

It seems that something went wrong when adding the reference to the docker repository.

What output do you receive for the following commands:

uname -a
lsb_release -crid
grep -i docker /etc/apt/sources.list /etc/apt/sources.list.d/*.list
cat -n /etc/apt/sources.list.d/docker.list
. /etc/os-release && echo "$VERSION_CODENAME"

1. You missed that there is a dot at the beginning of the last command.

2. What output do you now receive for the command
sudo apt update

luis@l-System-luisj:~$ . /etc/os-release && echo "$VERSION_CODENAME"
jammy
luis@l-System-luisj:~$

Repeating:

What output do you now receive for the command
sudo apt update

Apologize for the mistake

luis@l-System-luisj:~$

Now it looks correct ("Hit:3 https://download.docker.com/linux/ubuntu jammy InRelease")

What happens now, when you do the next step and try installing the docker packages:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

and then test your installation by running the hello-world image:
sudo docker run hello-world

Running the hello-world I hope this is correct.

luis@l-System-luisj:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Thanks Manfred Hampl, that solved my question.
