Vamos a provocar que la Raspberry PI se autoactualice:
sudo apt-get install unattended-upgrades
Añadimos en el fichero:
`sudo vi /etc/apt/apt.conf.d/10periodic`
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";
```
Y cambiamos (si aparece) en:
```
`sudo vi` `` `/etc/apt/apt.conf.d/50unattended-upgrades` ``
```
```
`` `"origin=Debian,archive=stable,label=Debian-Security";` ``
```por esto otro:
```
``` `` `"origin=Raspbian";` `` ```
```
```
Para Ubuntu hay que seguir [estas instrucciones](https://help.ubuntu.com/community/AutomaticSecurityUpdates#Using_the_.22unattended-upgrades.22_package).
