Cannot update GeoGebra

New to ZorinOS and testing the education platform. GeoGebra won't update. I tried the purge command to uninstall it and the system said it was installed. Any help would be greatly appreciated

Hi,

Please post the output of this this command

apt search geogebra

You can download the Classic 6 version from here:

Did you use the purge command correctly?
