title: Gestion des clés apt
#### Clé publique non disponible / reconnue ####
Lors de l'utilisation d'*apt*, il arrive d'obtenir l'erreur suivante:
```
W: GPG error: <URL> Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY <PUBKEY>
```
Cela signifie que la signature du dépôt n'a pas pû être vérifiée localement.
Il faut donc ajouter la clé publique du dépôt.
##### Ajout via //apt-key// #####
```
root@test01:~ # apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <PUBKEY>
```
##### Méthode alternative #####
Il est également possible de réaliser l'ajout de la clé publique via *gpg* :
```
root@test01:~ # gpg --keyserver pgpkeys.mit.edu --recv-key <PUBKEY>
root@test01:~ # gpg -a --export <PUBKEY> | apt-key add -
root@test01:~ # apt update
```

title: Connaître la liste des packages à upgrader
```
apt-get --just-print upgrade | grep -i security | awk '{print $2}' | awk '!seen[$0]++'
```
Exemple:
```
root@test01:~ # apt --just-print upgrade | grep -i security | awk '{print $2}' | awk '!seen[$0]++'
mariadb-common
libmariadb3
mariadb-client-core-10.5
mariadb-client-10.5
mariadb-client
```
Il suffira donc de mettre à jour ces paquets unitairement.
```
root@test01:~ # apt install mariadb-common libmariadb3 mariadb-client-core-10.5 mariadb-client-10.5 mariadb-client
