ROS cannot install Noetic due to unmet dependencies 20.04
Hi all,
Today I've tried installing ROS Noetic on a fresh install on 20.04 Ubuntu. Following the instructions on the ROS wiki for installation. I've now tried this both in a VM on a desktop, and without a VM on a laptop. Both with fresh installs on 20.04 LTS. In both setups I am met with the error:
sudo apt install ros-noetic-desktop-full
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ros-noetic-desktop-full : Depends: ros-noetic-simulators but it is not going to be installed
Depends: ros-noetic-urdf-sim-tutorial but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Does anyone know how to correct this?

aptitude
in place ofapt
might be a good start.
