Problèmes SSH (ssh_exchange_identification: lire: connexion réinitialisée par un homologue)

J'utilisais la version 11.10 et ai décidé d'effectuer la mise à niveau complète et d'arriver à la version 12.04 après que la mise à jour SSH (et non la disque dur SSHD) se soit mal déroulée lors de la tentative de connexion à d'autres instances OpenSSH. Je dis OpenSSH car j'utilise un sshd DropBear sur mon routeur et je peux me connecter.

Lors de la tentative de connexion à un serveur OpenSSH

J'ai cherché sur Google et exécuté la plupart des solutions recommandées à la fois du côté de Debian et du côté de Arch et aucun ne semble résoudre mon problème. Des idées?

On dirait que j'ai peut-être retrouvé cela sur un périphérique réseau qui n'est plus sain d'esprit.
