Problem installing any package
Hello! I am a newbie to ROS. Please bear with me.
Edit 1: I am unable to install any package now. I tried installing Turtlebot Simulator and I am getting the same error. I think there is some problem with ROS itself.
I am unable to install jackal simulator from clearpathrobotics. I get the following error -
E: Unable to locate package ros-indigo-jackal-simulator E: Unable to locate package ros-indigo-jackal-desktop
I am not sure why this is happening as I have ROS Indigo installed and running Ubuntu 14.04.3 LTS. I tried the installation after sudo-apt-get-update, and still I get the same error.
Can anyone please tell why I am unable to install?
Thank you.
Did you install ROS through apt-get? Are you using ARM or x86?
Thru apt-get
Have you modified your /etc/apt/sources.list or any of the files in /etc/apt/sources.list.d/ since you installed ROS?
No. I have not modified the sources.list file. And there are no files in sources.list.d
