This release fixes many security issues and users should upgrade as soon as possible.


New features

  • You can now lock your screen by clicking on the Lock button in the system menu.


    • If you set up an administration password when starting Tails, you can unlock your screen with your administration password.

    • Otherwise, you can set up a password to unlock your screen when locking your screen for the first time.


  • We improved a lot the backend of the Additional Software persistence feature. Your additional software is now:

    • Installed in the background after the session starts instead of blocking the opening of the desktop.
    • Always installed even if you are offline.
  • Install pdf-redact-tools, a command line tool to clean metadata and redact PDF files by converting them to PNG images.

  • An error message indicating the name of the graphics card is now displayed when Tails fails to start GNOME.

  • Upgrade Electrum from 2.7.9 to 3.0.6.

  • Upgrade Linux to 4.15.0.

Known issues

  • Tails Verification, our browser extension to verify Tails downloads, is broken in Tails 3.6. Please use it from Firefox, Chrome, or Tor Browser outside of Tails. (#15434)

  • Enigmail is unable to download OpenPGP keys for new contacts if you have the GnuPG persistence feature activated. You can still download OpenPGP keys using Passwords and Keys. (#15395)

  • This release is not reproducible, due to various python files in /usr/local having different timestamps. (#15400)

See the list of long-standing issues.

Get Tails 3.6

  • We do not provide automatic upgrades from older Tails installations for this release, as we've hit an old bug while generating the necessary files (#13426). You have to upgrade manually.

    If you are doing a manual upgrade from Tails 3.2, 3.3, 3.4, or 3.5, it is only possible to select an ISO image when running Tails in English. For other languages, the file chooser button remains inactive:

    To do a manual upgrade from Tails 3.2, 3.3, 3.4, or 3.5, you can either:

    • Restart Tails in English.

    • Start Tails Installer in English from the command line:

      LANG=en_US tails-installer
  • Download Tails 3.6.
