Apt update error in ros2-latest.list

Question

I'm trying to run sudo apt update

And I get this message E: Malformed entry 1 in list file /etc/apt/sources.list.d/ros2-latest.list (Component) E: The list of sources could not be read.

Here is /etc/apt/sources.list.d/ros2-latest.list content:

deb [arch=amd64,arm64] http://repo.ros2.org/ubuntu/main main

Here is sources.list content:

# deb cdrom:[Ubuntu 20.04.1 _Focal Fossa_ - Release amd64(20200808.1)]/ focal main restricted

Does this answer your question? E: Malformed entry 54 in list file /etc/apt/sources.list (Component) — karel, Feb 11 '23 at 08:44
Since you don't show us the content of /etc/apt/sources.list.d/ros2-latest.list it is difficult to to say whats wrong. — Soren A, Feb 11 '23 at 08:54
I'm new to linux and I don't know the malformed entry there, could u help me find it? — Ahmed Ismail, Feb 11 '23 at 09:11
If you post the contents of that file to your question, someone will tell you what is wrong. That's what everyone is telling you. — Pilot6, Feb 11 '23 at 09:32
Why don't you read comments and your own question? We need contents of another file. You got an error message that something is wrong in /etc/apt/sources.list.d/ros2-latest.list. You're asking to help you to find out what is wrong. Why is it so difficult to provide contents of that file? — Pilot6, Feb 11 '23 at 09:46
Sorry I told you that I'm completely new to Ubuntu, I didn't mange to access this file at first as I told you. But I did and updated the question with its content. — Ahmed Ismail, Feb 11 '23 at 09:53
@AhmedIsmail You updated with the contents of the wrong file. Look at your error message, it clearly states which file is wrong: /etc/apt/sources.list.d/ros2-latest.list. — mook765, Feb 11 '23 at 14:13

The line in /etc/apt/sources.list.d/ros2-latest.list is wrong.

Change it to

deb [arch=amd64] http://repo.ros2.org/ubuntu focal main

You can do it by running

sudo nano /etc/apt/sources.list.d/ros2-latest.list

Ctrl+O to save Ctrl+X to exit.
