Can not install Gazebo 7 or 8 on Ubuntu 16.04
When I tried to install of Gazebo 8 with the tutorials, I had the broken packages (held). Then I tried to install of Gazebo 7. And the package gazebo-common cant be installed. The download freezes. When I tried to download packages from link:[http://gazebosim.org/download] - version 7.1 I've get "fatal error" when I try to open it. Any idea what can I do to install gazebo?
