Tails includes an automatic mechanism to upgrade a USB stick to a newer version. In some cases, it is impossible to do an automatic upgrade and you might have to do a manual upgrade. This page describes both techniques.

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.

Checking which version of Tails you are currently running

To check which version of Tails you are currently running, choose Applications ▸ Tails ▸ About Tails.

Automatic upgrade using 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.

مزایای این روش عبارتند از:

  • 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.

موارد موردنیاز:

  • A Tails USB stick.
  • اتصال به اینترنت.

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

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:



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.

Manual upgrade using Tails Installer

ممکن است همان‌طور که در بالا اشاره شد ممکن است ارتقای خودکار همیشه ممکن نباشد برای نمونه، هنگامی که:

  • در تارنمای ما هیچ ارتقای خودکاری برای این نسخه وجود ندارد.
  • 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:

Download and upgrade

You need:

  • Your Tails USB stick
  • Another empty USB stick (at least 8 GB) Why?
  • 1 hour to download Tails ( 1.1 GB )
  • ½ 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.

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.

You need:

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