when i typed sudo apt-get update in terminal, it gave me this error:

E: Malformed line 1 in source list /etc/apt/sources.list.d/gazebo-latest.list (dist)
E: The list of sources could not be read.

I looked into gazebo-latest.list file. there is a line 

deb http://packages.osrfoundation.org/gazebo/ubuntu quantal main

How can i fix this problem

First of all Quantal is an end of life Ubuntu release and not supported now, So upgrade your system into any supported release .

And solution for this problem is already discusseed here, but putting a / after ubuntu in the gazebo-latest.list (i.e deb http://packages.osrfoundation.org/gazebo/ubuntu/ quantal main) should also work.

(Note: you will still get error in update because of being an unsupported release so again upgrade your system into a supported release. See How to install software or upgrade from old unsupported release? )

  • im running ubuntu 14.04. not sure why quantal is in the file. Can you explain please? – Minh Nguyen Jan 22 '15 at 10:53
  • If you are running 14.04, instead of quantal there should be trusty in your gazebo-latest.list file. It represent the version of ubuntu you are using while resynchronizing your software index with server (like when you use sudo apt-get update). Edit this line to look like deb http://packages.osrfoundation.org/gazebo/ubuntu/ trusty main. It should work. Also mention that you are using 14.04 in your question by editing it, so that it will not be marked as duplicate. – g_p Jan 22 '15 at 11:04
  • Thanks, seems like i dont have permission to change the file. It says permission to write is owner root only. How can i log in as root ? – Minh Nguyen Jan 22 '15 at 22:30
  • enter sudo nano /etc/apt/sources.list.d/gazebo-latest.list to open this file in editor. Edit it and press Ctrl+o to save and Ctrl+x to exit. – g_p Jan 23 '15 at 01:51
