Tails include un meccanismo automatico per aggiornare una chiave USB a una nuova versione. In alcuni casi è impossibile effettuare un aggiornamento automatico e potresti dover effettuare un aggiornamento manuale. Questa pagina descrive entrambe le tecniche.

Your persistent storage will be preserved by both automatic and manual upgrades.

If you use Tails from a DVD, you need to burn a new DVD.

Aggiornamento automatico usando Tails Upgrader

After starting Tails and connecting to Tor, Tails Upgrader automatically checks if upgrades are available and then proposes you to upgrade your USB stick. The upgrades are checked for and downloaded through Tor.

I vantaggi di questa tecnica sono i seguenti:

  • You only need a single Tails USB stick. The upgrade is done on the fly from a running Tails. After upgrading, you can restart and use the new version.
  • The upgrade is much smaller to download than a full USB image.
  • The upgrade mechanism includes cryptographic verification of the upgrade. You don't have to verify the USB image yourself anymore.

Requisiti:

  • A Tails USB stick.
  • Una connessione a internet.

After connecting to Tor, if an upgrade is available, a dialog appears and proposes you to upgrade your USB stick.

Se decidi di effettuare l'aggiornamento, clicca su Aggiorna ora, e segui l'assistente attraverso il processo di aggiornamento.

If you missed an upgrade, each upgrade will be installed one after the other.

For example, if you have a Tails 4.1 and the current version is 4.5, then the upgrade to 4.3 will be installed, and after you restart Tails, the upgrade to 4.5 will be installed.

If you cannot upgrade at startup (for example, if you have no network connection by then), you can start Tails Upgrader later by opening a terminal and executing the following command:

tails-upgrade-frontend-wrapper

Risoluzione di problemi

If an error occurs during the upgrade, the assistant proposes you to read one of the following pages:

If your Tails USB stick fails to start after an automatic upgrade, see below how to do a manual upgrade.

Aggiornamento manuale usando Tails Installer

Potrebbe non essere sempre possibile effettuare un aggiornamento automatico come descritto sopra. Per esempio, quando:

  • Nessun aggiornamento automatico è disponibile dal nostro sito per quella versione.
  • The automatic upgrade is impossible for technical reasons (not enough memory, not enough free space on the USB stick, etc.).
  • The automatic upgrade failed and you need to repair a Tails USB stick.
  • You want to upgrade by cloning from another Tails USB stick which is already up-to-date, for example, when working offline or with a slow Internet connection.

After connecting to Tor, a dialog informs you if you have to upgrade your USB stick using Tails Installer to a newer version of Tails.

To do a manual upgrade, you can either:

Upgrade by cloning from another Tails

If you know someone you trust who already did the upgrade, you can upgrade your Tails by cloning from their Tails.

  • Your Tails USB stick - Another up-to-date Tails (USB stick or DVD) - ¼ hour to upgrade

It is currently impossible to manually upgrade a Tails USB stick while running from itself. This scenario requires creating an intermediary Tails on another USB stick, from which to upgrade your Tails.

Downloading and upgrading from Windows might be less secure if your Windows is compromised but it might be more convenient and faster to download.
