follow the melodic installation guide key in the code

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

my computer shows illegal option

I am sure these 3 repositories "restricted," "universe," and "multiverse" are allowed. but I got "failed to download repositories information" when I tried to download it I changed different server but the result is the same.

I got the message my RAM may not be large enough. is this the reason ?

I removed the old key and key in the new key the screen shows

You don't need any points, as we don't ask you for a screenshot, but a copy-paste of the text of the error message.

Can you try the following command:

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

and afterwards show us the output of

cat /etc/apt/sources.list.d/ros-latest.list

just copy-paste the output of the last command (and any errors you get from the first) into your question.

Use the edit button/link for that.

After I key in the command:echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/ros-latest.list the result is deb http://packages.ros.org/ros/ubuntu xenial main

Ok.

That is good.

Now try a sudo apt update, and show us the output here.

I'm confused by your last edit. Did you intend to show us an update?

I'm not entirely sure what the problem with the ftp.nsysu.edu.tw host is, but at least for packages.ros.org you don't appear to have the correct key imported.

Refer to #q325039 for instructions on how to fix that.

Then run a sudo apt update again.


Edit:

and try sudo apt update it still not works:

E: The repository 'http://ftp.nsysu.edu.tw/Ubuntu/ubuntu xenial Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

This is not a problem with the ROS package repositories, but with the ftp.nsysu.edu.tw host.

Do you know what ftp.nsysu.edu.tw is? Try using a different host.

In any case: the problem with the ROS package repositories seems to be fixed: you now have the correct key imported.
