Ros on fedora can't communicate publisher/subscriber

edit

Hello,

I'm using the fedora repo given by @cottsay. I might be doing something stupid but it seems to me that the messages are not working fine.

if I do :

roscore

then

rostopic echo /search

then

rostopic pub -1 /search std_msgs/Bool 'data : False'

Nothing is received. I got the good number of node if I do a rosnode list and when using rostopic info search I can see a node subscribing to the topic. I might do something incredibly stupid, but for now I did not find what is the problem and I don't really know what to do to debug it...

EDIT : Still having that problem. This is my repolist :

I did yum install ros-hydro-desktop-full. I think it might be depend on my computer and not on ros itself but I have no idea what causes this. Here is a screenshot of what I'm doing :

And nothing is received.

Here is my .bashrc as well concerning hydro :

alias hydro='source /opt/ros/hydro/setup.bash && source /home/malcolm/ros_ws/catkin_hydro/devel/setup.bash && export EDITOR='nano' && export ROS_PACKAGE_PATH=/home/malcolm/ros_ws/catkin_hydro/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks

and the env variable of my system :

declare -x ROSLISP_PACKAGE_DIRECTORIES="/home/malcolm/ros_ws/catkin_hydro/devel/share/common-lisp"
declare -x ROS_DISTRO="hydro"
declare -x ROS_ETC_DIR="/opt/ros/hydro/etc/ros"
declare -x ROS_MASTER_URI="http://localhost:11311"
declare -x ROS_PACKAGE_PATH="/home/malcolm/ros_ws/catkin_hydro/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks"
declare -x ROS_ROOT="/opt/ros/hydro/share/ros"
declare -x ROS_TEST_RESULTS_DIR="/home/malcolm/ros_ws/catkin_hydro/build/test_results"

EDIT : It seems more like my system is strangely slow. I'v launch a bunch of node right now and each time I'm trying to have the tf with this command : cd /var/tmp && rosrun tf view_frames && evince frames.pdf I either have no tf data, or partial tf data, not always the sames... which makes me thing that it may just be very slow...
