L’erreur se produit à la ligne 1049 de /usr/bin/distrobox-create, où la variable RECYCLE est référencée mais n’est pas définie. Commencez par examiner le script autour de cette ligne afin d’en comprendre le contexte. Cherchez où RECYCLE devrait être définie, éventuellement dans une fonction ou un bloc conditionnel. Vérifiez la logique du script pour la création et le recyclage des conteneurs. Exécutez le script avec le débogage (set -x) pour suivre l’affectation de la variable et voir pourquoi RECYCLE n’est pas liée.
