I am using command sudo apt-get update and this error is coming. How to solve this issue?
Malformed entry 1 in list file /etc/apt/sources.list.d/ros-latest.list (Component)
E: The list of sources could not be read.
I am using ubuntu 18.04 and ros melodic.
ros-latest.list content:-
deb http://packages.ros.org/ros/ubuntu main
Malformed entry 1 in list file /etc/apt/sources.list.d/ros-latest.list (Component) E: The list of sources could not be read.
Something probably went wrong during initial setup of the ROS package repository sources. Most likely this section of the tutorial.
Can you show us the contents of ros-latest.list? Use the following command:
cat /etc/apt/sources.list.d/ros-latest.list
and copy-paste the text from the terminal into your original question text. Use the edit button/link for that.
Edit:
ros-latest.list content:-
deb http://packages.ros.org/ros/ubuntu main
I have the impression that this is missing the Ubuntu code name for the release, which in your case probably should be bionic (provided you are actually running Ubuntu Bionic (ie: 18.04).
To make sure: what is the output of:
lsb_release -sc
If that returns an error, or tells you the command lsb_release can't be found, then that is most likely what went wrong. If the command can't be found, install it using sudo apt install lsb-release.
Edit 2:
it is showing output :- bionic
Then something must have gone wrong while executing this line from this section of the tutorial:
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
Can you run this again and check carefully whether any warnings and/or errors are printed?
You can fix the issue by following below steps:
Open your /etc/apt/sources.list.d/ros-latest.list file and comment the line.
Install lsb_release by running apt-get install lsb_release.
Then you can follow the usual procedure for ROS installation.
Thank you, KK
Hi kk2105. I apologize for the delay. I was trying desperately to fix the issue. Here are the contents:
http:packages.ros.org/ros/ubuntu main
I appreciate your help. I have used Linux for years, and this is my first time to be unable to sudo apt-get update. When I use that, get the following:
E: Malformed line 1 in source list /etc/apt/sources.list.d/rehinkdb.list (type)
E: Malformed entry 1 in list file /etc/apt/sources.list.d/ros-latest.list (Component) E: The list of sources could not be read.
