I followed the instruction given here https://kolibri.readthedocs.io/en/latest/install/raspberry_pi_manual.html to install kolibri.
I want to also deploy Kiwix alongside kolibri for offline access of wikipedia for the students.
I tried running command sudo apt install kiwix kiwix-serve
But it is resulting in error
E: Unable to locate package kiwix
Please guide on this
