How to install:

sudo apt install sqlite3 akonadi-backend-sqlite akonadi-server kdepim-runtime zanshin

Beware that kdepim-runtime package includes lots of dependencies, it's powerful infrastructure that provides essential runtime components and services that are required for the proper functioning of KDE PIM applications. These applications include email clients, address books, calendars, and other tools designed to help users manage their personal information effectively.

akonadi-backend-sqlite is not the only backend available for akonadi, in fact akonadi-backend-mysql is recommended.

After that start akonadi-server manually once (as user, not root):

akonadictl start

To verity run

akonadictl status

You should see that server and control are running AND “Available Agent Types” are present and include akonadi_akonotes_resource, akonadi_ical_resource, akonadi_notes_resource
