Due to project requirements, I cannot change the OS version
Please find the installation commands used
voxl2:/$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
voxl2:/$ sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
voxl2:/$ sudo apt update
voxl2:/$ apt install -y ros-melodic-ros-base ros-melodic-image-transport

The voxl2 board has the Ubuntu 18.04.5 LTS OS on it.
So I installed ROS Medolic as mentioned in https://docs.modalai.com/ros-installation-voxl2/

Then I tried installing the ros packages using the following command
sudo apt-get install -y ros-melodic-pcl-ros ros-melodic-pcl-conversions
but the installation is getting stuck at Setting up python-twisted-core (17.9.0-2ubuntu0.3)

I ran tail -f /var/log/dpkg.log to check the status which showed
configure python-twisted-core:all 17.9.0-2ubuntu0.3 <none>
status half-configured python-twisted-core:all 17.9.0-2ubuntu0.3

Hello

I have installed ROS in VOXL 2 board using the instructions in the link https://docs.modalai.com/ros-installation-voxl2/.
When I tried installing ros-melodic-PCL-conversions it took more than 30 minutes trying to install python-twisted-core

Are there any alternatives or steps I am missing ...
