Vous devriez essayer d'utiliser xhost

Le programme xhost est utilisé pour ajouter et supprimer des noms d'hôte ou des noms d'utilisateur à la liste autorisée à établir des connexions avec le serveur X. Dans le cas des hôtes, cela fournit une forme rudimentaire de contrôle et de sécurité de la confidentialité. Il ne suffit que pour un environnement de poste de travail (utilisateur unique), bien qu'il limite les pires abus. Les environnements qui nécessitent des mesures plus sophistiquées doivent implémenter le mécanisme basé sur l'utilisateur ou utiliser les crochets du protocole pour transmettre d'autres données d'authentification au serveur

xhost affichera la liste des noms autorisés

$ xhost
access control enabled, only authorized clients can connect
SI:localuser:yourusername

xhost +si:localuser:root devrait vous aider dans votre cas.

Et après cela, vous verrez

$ xhost
access control enabled, only authorized clients can connect
SI:localuser:root
SI:localuser:yourusername

Et Sudo wifi-radar fonctionnera comme prévu.

C'est à peu près l'une des raisons pour lesquelles vous pouvez voir ce message d'erreur.
