We would like to thank you for your interest to be a participant of Ludus project with Turris 1.x router. Package libmaxminddb is not available for Turris 1.x. due to compile issues. Because of that, it is just available for Turris Omnia owners in Turris OS 3.x release.
@paja is working to have Ludus package also on Turris OS 4.x. release.
