Au lancement de la mise \u00e0 jour des paquets du serveur, je suis tomb\u00e9 sur le message d\u2019erreur suivant :<\/p>\n\n\n\n

Visiblement, APT a perdu ses petits et ne retrouve plus la cl\u00e9 publique GPG d\u2019un des mes d\u00e9p\u00f4ts (webmin en l\u2019occurence).<\/p>\n\n\n\n
Voici comment rem\u00e9dier au probl\u00e8me.<\/p>\n\n\n\n
Solution : demander et ajouter la cl\u00e9 au trousseau GPG<\/h2>\n\n\n\n
Un peu de m\u00e9nage dans APT<\/h3>\n\n\n\n
On commence par faire un peu de m\u00e9nage dans les fichiers APT avec un petit coup de balai:<\/p>\n\n\n\n
apt-get clean<\/pre>\n\n\n\n
\u2026 avant de r\u00e9cr\u00e9er le dossier lists\/partial pour v\u00e9ritablement recr\u00e9er le cache APT :<\/p>\n\n\n\n
cd \/var\/lib\/apt\nmv lists lists.old\nmkdir -p lists\/partial\napt-get clean && apt-get autoremove && apt update<\/pre>\n\n\n\n
Import de la cl\u00e9 publique<\/h3>\n\n\n\n
Maintenant, il nous reste \u00e0 importer la cl\u00e9 publique manquante dans notre trousseau.<\/p>\n\n\n\n
On se place dans le dossier root pour travailler:<\/p>\n\n\n\n
cd \/root<\/pre>\n\n\n\n
On demande la cl\u00e9 publique:<\/p>\n\n\n\n
gpg --recv-keys 8B48AD6246925553<\/pre>\n\n\n\n
On l\u2019exporte et on l\u2019ajoute \u00e0 notre trousseau :<\/p>\n\n\n\n
gpg --export 8B48AD6246925553 | apt-key add -<\/pre>\n\n\n\n
On peut alors relancer la mise \u00e0 jour des paquets :<\/p>\n\n\n\n
apt-get clean && apt-get autoremove\napt update && apt upgrade<\/pre>\n\n\n\n
Script bash pour automatiser la mise \u00e0 jour des cl\u00e9s APT<\/h2>\n\n\n\n
Soyons plus fous, nous allons automatiser les deux commandes avec un petit script BASH. On cr\u00e9e notre script :<\/p>\n\n\n\n
nano \/home\/scripts\/renew-apt-key<\/pre>\n\n\n\n
et on y ajoute:<\/p>\n\n\n\n
#!\/bin\/bash\n# Author : Matt Biscay\n# Author URI : https:\/\/www.skyminds.net\/?p=8735\ngpg --keyserver keyserver.ubuntu.com --recv-keys $1\ngpg --armor --export $1 | sudo apt-key add -<\/pre>\n\n\n\n
On enregistre le fichier et on le rend executable :<\/p>\n\n\n\n
chmod +x renew-apt-key<\/pre>\n\n\n\n
Il ne vous reste plus qu\u2019\u00e0 renouveler votre cl\u00e9 APT avec:<\/p>\n\n\n\n
sudo .\/renew-apt-key NUMERO-DE-CLE<\/pre>\n\n\n\n
Et voil\u00e0, plus d\u2019erreur lors des mises \u00e0 jour APT.<\/p>\n\n\n\n
