Known issues

  • 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)

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.

What's coming up?

Tails 3.7 is scheduled for May 8.
