Actualizando Pi-hole de versión

Difunde No Solo Hacking!

Los que ya me conocéis sabréis que el tema de la privacidad me lo tomo muy enserio y me preocupa mucho. Fue por esto una de las razones que me compré una Raspberry Pi, para instalar Pihole y probarlo.

Para los que no lo conozcan, es una herramienta muy útil que lo que hace es bloquear la resolución DNS de ciertos sitios que se dedican a hacer tracking.

Y haré un día un post de cómo ir mejorando estos aspectos en nuestro entorno y tener un mejor nivel de privacidad. La verdad es que es una herramienta indispensable en toda casa.

Panel administración de Pihole

Desde que lo instalé, han liberado alguna versión nueva, por lo que voy a dedicar este artículo a explicaros cómo actualizarla.

Lo primero que debemos saber es si hay otra versión más reciente que la que tenemos instalados. Para ello nos vamos al panel de administración en un navegador web de nuestro Pi-hole.

Ahí podemos ya ver si hay o no una nueva versión

Otra manera de hacerlo es desde la consola de comandos, ejecutar el comando:

pihole -v

El output del comando, como véis, nos va a dar la versión que corremos para sus 3 componentes y si hay otra más reciente.

Para poder hacer el update de la versión, solo hace falta que corramos el comando:

pihole -up

Esto lo que hará es comprobar si hay una versión, comprobar los paquetes que hay que actualizar, dependencias…. Después se pondrá con la actualización.

Por último nos dirá que hay un log para comprobar, en caso de errores o simplemente, que queramos ver que se ha hecho, en la ruta:

/etc/pihole/install.log

Espero que os haya gustado y sobre todo, recordad que debéis siempre mantener tanto el sistema operativo como todo el softwar totalmente actualizado.
