Hi, I am using UBUNTU 18.04. I followed the steps in http://wiki.ros.org/melodic/Installat... up to the section 1.4. I am now hesitating between the different packages suggested. To start with, I would prefer to install the smallest number of packages required to run the tutorials and get familiar with the whole concept.

If I install "ROS-Base", which additional "Individual Package" will be needed?

Thanks for your help

You can start with ROS-Base and add any necessary packages later, as you need them. Which packages depends on the tutorials you want to follow. I don't think the first few ROS Tutorials require additional packages, but I haven't thoroughly read them in a long time. I think you can get through several with just rqt, but each tutorial should state prerequisites. If you end up not having a required package, you can install it easily. For example, the Understanding ROS Nodes tutorial requires you to install a package with

sudo apt-get install ros-melodic-ros-tutorials

Thanks Tryan for your helpful answer! Is the installation of rqt already included in the ROS-Base package?

I think it's only included in the desktop variants, but you can still install it separately when necessary. Here's REP 142 defining the different variants, and here's the metapackages GitHub repo for more details.
