J'ai exécuté une commande potentiellement dangereuse et imprévisible, et j'ai besoin d'aide pour annuler les modifications qu'elle a pu apporter. Sans réinstaller Ubuntu si possible. Je dois m'assurer que je n'ai pas eu de problèmes de compatibilité en installant de vieux logiciels. Car si c'est le cas, je risque d'avoir beaucoup de bugs et de problèmes à l'avenir, et ce sera la cause.
La situation : J'essayais de résoudre des problèmes MIDI. J'ai donc trouvé cette page a trouvé cette commande et l'a exécutée :
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2J'ai donné l'autorisation à la racine après qu'on me l'ait demandée. Et le plus dangereux, c'est que même si la commande est suggérée sur une page d'aide d'Ubuntu, la page elle-même dit qu'il est dépassé au sommet et qu'il ne devrait pas être utilisé plusieurs fois.
Il s'agit de l'invite officielle (qui commence par la commande tapée). Pouvez-vous me dire si cela a endommagé ma machine ? Je pense qu'il a pu installer de très vieux logiciels, car l'instruction était dans le tutoriel qui n'était pas recommandé. Comment puis-je revenir à la situation antérieure ? Ou tout simplement il n'y a pas de problème ?
