无法为Indigo下载ROS Gazebo 7程序包

Question

I'm having some trouble with installing gazebo7_ros_packages for ROS Indigo and Gazebo 7.9 on Ubuntu 14.04 LTS. I followed this tutorial. I typed this

sudo apt-get install ros-indigo-gazebo7-ros-pkgs

The apt installer says the following

Unable to locate package ros-indigo-gazebo7-ros-pkgs

I had run sudo update and upgrade before this, and my repositories and keys have been set as given here .

So I tried to clone from OSRF's git from https://github.com/osrf/gazebo7_ros_pkgs-release/tree/debian/indigo/gazebo_ros_pkgs , but I'm only able to pull only one branch at a time. Then I followed this tutorial. This is what I get. Keep in mind, I'm using gazebo 7.9.

I commented on the same question here

To quote him:

I don't know the details about your environment, but ros-indigo-gazebo7-ros-controlis being successfully installed by our daily testing job: https://build.osrfoundation.org/job/ros_gazebo7_pkgs-install_pkg_indigo-trusty-amd64/274/consoleFull

The URL denotes that it's for a 64 bit machine. I did some poking around on that site and I found out that there are no pkgs for a 32 bit version/i386. I am running Ubuntu 14.04 32 bit on a 64 bit Intel Celeron 900. Could that be the problem? Lack of packages for i386 processors?

Answer 1

Have You removed Gazebo 2.* ? if u didn't already do :

sudo apt-get purge gazebo*

after that add the osrf official repo and update:

sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable lsb_release -cs main" > /etc/apt/sources.list.d/gazebo-stable.list'

wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -

sudo apt-get update

and install :

sudo apt-get install ros-indigo-gazebo7-ros-pkgs

found it here on github

Answer 2

The issue, as I guessed, was because of the 32 bit installation of Ubuntu. I reinstalled with a 64 bit version, and it works fine now.
