Comment mettre à jour Pi-hole sur votre Raspberry

Dans cet article rapide, qui ne mérite pas de vidéo, je vais vous présenter les trois commandes nécessaires pour faire une mise à jour de Pi-hole sur votre Raspberry-Pi.

Qu'est-ce que Pi-hole ?

Si vous tombez sur cet article par le plus grand des hasard, je vous invite à regarder mon tutoriel d'installation de Pi-hole sur un Raspberry Pi.

Pour faire simple, Pi-hole vous permettra de bloquer les publicités et le tracking sur Internet à l'échelle de votre réseau. Très puisant et très facile à mettre en place. Sauf que ce matin, j'avais ce message, attirant mon attention :

C'est rouge et ça clignotte : ça a l'air important

Je vous propose de voir comment on met Pi-hole à jour. Rassurez vous, c'est très rapide.

Tutoriel de mise à jour

La première des choses à faire est de se connecter en SSH sur votre Raspberry Pi, avec l'utilisateur "pi", par exemple. Dans mon cas ce sera l'utilisateur "lokan".

ssh lokan@192.168.10.200

Maintenant que vous êtes connecté, on peut commencer. Une simple commande va vous permettre de vérifier l'état des mises à jour de votre Pi-hole :

pihole -v

lokan@vignemale:~ $ pihole -v
Pi-hole version is v5.2.4 (Latest: v5.3.1)
AdminLTE version is v5.4 (Latest: v5.5)
FTL version is v5.7 (Latest: v5.8.1)

Ça confirme donc qu'il y a de la mise à jour à passer.

Il suffit de faire un pihole -up pour initier la mise à jour. Voici le résultat :

lokan@vignemale:~ $ pihole -up

Update Complete!

Un dernier pihole -v pour vérifier que vous êtes à jour :

lokan@vignemale:~ $ pihole -v
Pi-hole version is v5.3.1 (Latest: v5.3.1)
AdminLTE version is v5.5 (Latest: v5.5)
FTL version is v5.8.1 (Latest: v5.8.1)

Conclusion

Voilà. C'est aussi simple qu'une connexion SSH, une vérification de version et une commande "up" pour faire la montée de version.

Ce tutoriel, comme beaucoup d'autres, est là en pense-bête personnel. S'il peut vous aider en même temps, c'est super cool.
