ROS indigo Installation Dependency issue
I am trying to install ROS Indigo in ubuntu: http://gazebosim.org/tutorials/?tut=d... When I give the following install command in my terminal:
# Install osrf-common's dependencies
sudo apt-get install -y cmake \
debhelper \
ros-indigo-ros \
ros-indigo-ros-comm
the output messages i get is
> debhelper \
> ros-indigo-ros \
> ros-indigo-ros-comm

cmake is already the newest version (3.16.3-1ubuntu1).
debhelper is already the newest version (12.10ubuntu1).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

Can you clarify what the host OS is? 20.04 is not supported by Igloo. You may want to consider changing ROS distros or changing your operating system to one with Tier 1 support for Igloo. I would suggest not using Igloo as it is end-of-life.
Why do you want to use such an old version of ROS?
It might because many older robots like kuka youbot never been updated to newer ros distros. even I use Hydro just to work on kuka youbot. And now I can not even download the ros hydro on new PC. I just have to use what is already installed few years back.
