==== Remove Unused Software ====
from a Raspian Buster (Debian 10)

After burning a new SD card one finds quite a huge, already installed software package. To get more space on the SD card one can remove all unloved and unused packages. For example these:\\

   $ sudo apt update
   $ sudo apt remove --purge claws-mail minecraft libreoffice-core wolfram-engine
   $ sudo apt autoremove

That will save around 2 GB of space.\\
