Comment installer netcat sur Termux?

Je veux utiliser WireGuard sur mon téléphone pour me connecter au serveur WireGuard de mon bureau sur mon bureau. Sur un autre site Web, on m'a conseillé d'exécuter dans Terminal (j'utilise l'application Termux) sur mon téléphone, la commande nc -4u -w1. Je reçois "Le programme nc n'est pas installé. Installez-le en exécutant pkg install netcat". Lorsque j'essaie d'installer netcat, j'obtiens différents problèmes de référentiels et netcat n'est pas installé.

$ pkg install netcat
