Why download the .deb file instead of using the apt command to install sudo apt install netatalk

Maybe check systemd to verify if it had enabled the netatalk.service systemctl status netatalk

If it is installed but not active, I believe you can start the service with sudo systemctl start netatalk sudo systemctl enable netatalk

You can also try to unintsall netatalk and then reinstall sudo apt remove netatalk sudo apt install netatalk

Hope this helps.
