Tails 包括了一個自動機制自 USB 隨身磁來更新昇級。在某些情況下,它可能不會 自動昇級 因此你必須透過 手動昇級。本頁會介紹這兩種方法。

我們的昇級版本會修復重大的安全問題,因此最好即時進行更新。

Both techniques only work if the upgraded USB stick, was installed using Tails Installer. The persistent storage on the USB stick will be preserved.

如果你是使用DVD來執行 Tails, 你必需要 燒錄一個全新的DVD.

If you use Tails from a USB stick installed from macOS using the command line, you need to reinstall.

自動使用Tails Upgrader進行昇級

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.

這個方式有以下的優點:

  • 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.
  • 這個昇級會比下載完整的映像檔小許多。
  • 這個昇級機制包含了密語查核。你自身不必再核驗這個ISO 映像檔。

需求:

  • A Tails USB stick, installed using Tails Installer.
  • 網路連線。

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

  • 建議在昇級時,先關閉所有的應用程式
  • 下載昇級可能會花上一點時間,從幾分鐘到數小時
  • 在完成下載昇級軟體後,網路會自動關閉

如果要進行昇級,請點擊 立即昇級, 然後依照昇級過程的指示操作

If you missed an upgrade, each upgrade will be installed one after the other. For example, if you have a Tails 1.3 and the current version is 1.3.2, then the upgrade to 1.3.1 will be installed, and after you restart Tails, the upgrade to 1.3.2 will be installed.

如果你無法自啟動時更新 (例如在離線的狀況下 ), 你可以在終端器下打開 Tails Upgrader ,然後執行以下指令:

使用 Tails Installers進行手動昇級

We recommend you read the release notes for the latest version. They document all the changes in this new version:

  • new features
  • problems that were solved
  • known issues that have already been identified

They might also contain special instructions for upgrading.

有時候並不能成功地如上所述地自動完成更新,例如當:

  • 我們的網站上並未提供此版本的自動昇級更新。
  • The automatic upgrade is impossible for technical reasons (not enough memory, not enough free space on the USB stick, etc.).
  • You want to upgrade from another Tails USB stick which already has a newer version installed, for example when working offline.
  • The automatic upgrade failed and you need to repair a Tails USB stick.

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 so, follow our manual upgrade instructions.
