In accordance with the instructions given by https://wiki.geogebra.org/en/Reference:GeoGebra_Installation, I tried installing geogebra by first using sudo apt-add-repository -u 'deb http://www.geogebra.net/linux/ stable main', and then sudo apt install geogebra-classic, but when I run the last command, I get the error message "Unable to locate package geogebra-classic". Any tips?

You have add their GPG key by

wget https://static.geogebra.org/linux/office@geogebra.org.gpg.key -O - | sudo apt-key add

and then rerun update and install package:

sudo apt-get update
sudo apt-get install geogebra-classic

First, add the GPG key, then the repository, and finally install by these commands:

$ wget https://static.geogebra.org/linux/office@geogebra.org.gpg.key -O - | sudo apt-key add
$ sudo apt-add-repository -u 'deb http://www.geogebra.net/linux/ stable main' 
$ sudo apt install geogebra-classic

Thus the latest Geogebra will be installed.

Another option is to try GeoGebra Discovery (which is maintained by me) that may address some Linux related issues. It is based on GeoGebra 5.0.641.0 (the classic Java-based user interface). It can be installed as a snap: https://snapcraft.io/geogebra-discovery.
