Contribute to Tails by testing our release candidate for Tails 4.19!

We are very excited about it and cannot wait to hear your feedback :)

What's new in 4.19~rc1?

Tails 4.19, scheduled for June 1, will completely change how to connect to the Tor network from Tails. We would like as many people as possible to test this beta version to be able to fix as many problems as possible before we release 4.19 to all users.

Over the years, we have identified many issues in how to connect to the Tor network from Tails, thanks to your feedback. With this beta, we are trying to solve the most important and pressing of these issues:

  • The lack of feeback while connecting to the Tor network.

  • The option to use Tor bridges has to be turned on in the Welcome Screen and cannot be changed afterwards.

  • The lack of default Tor bridges.

  • The previous configuration screen for Tor bridges wasn't accessible to people who use the screen reader.

  • The lack of guidance when Tails is not connected to a local network yet.

What's new since 4.19~beta1?

The Tor Connection experience has had several improvements and bugfixes since 4.19~beta1. For more details, read our changelog.

If you manually upgraded from Tails 4.12 or earlier to 4.19~beta1 and did the Thunderbird OpenPGP migration then your keys are not protected by the master password (#18316, Mozilla bug). They are still protected by the persistent storage's encrypting, but once that is unlocked the keys are unprotected. This should be fixed in the final Tails 4.19.

Get Tails 4.19~rc1

To upgrade your Tails USB stick and keep your persistent storage

  • Automatic upgrades to Tails 4.19~rc1 are available from versions 4.2 or later.

    If you installed 4.19~beta1 you should automatically be asked to upgrade the next time you start it.

    If you are running Tails 4.2 to 4.18, you can upgrade like this:

    1. Start Tails and set an administration password.

    2. Run this command in a Terminal:

      echo TAILS_CHANNEL=\"alpha\" | sudo tee -a /etc/os-release && \

      Enter the administration password when asked for the "password for amnesia".

    3. After the upgrade is applied, restart Tails and choose Applications ▸ Tails ▸ About Tails to verify that you are running Tails 4.19~rc1.

Download Tails 4.19~rc1

Download and install Tails 4.19~rc1 as usually.

All the data on this USB stick will be lost. Don't install Tails 4.19~rc1 on any USB stick that already has a Persistent Storage, upgrade instead.

What to test in Tails 4.19~rc1?

We know that Tails 4.19~rc1 still has many rough edges. But we still need your help to identify as many new problems as possible!

We're particularly interested in you testing diverse and rare network configurations:

  • When connecting to Tor without bridges fails.

  • When Tails is not connected to a local network yet.

  • When disconnecting from a Wi-Fi network with Internet connectivity and then reconnecting to a different Wi-Fi network without Internet connectivity.

  • When disconnecting from Wi-Fi network that don't require Tor bridges and the reconnecting to different Wi-Fi network that requires Tor bridges.

  • When connecting to a Tor bridge that works at first but then stops working.

  • When connecting to the Internet using a proxy.

Tell us if anything is unclear, confusing, or not working as you would expect.

Please, send your feedback to (public mailing list).

If you are comfortable with the command line, check our hacking tips. They contain firewall rules that can be used to block access to the Tor network without bridges or simulate a broken bridge.

Known issues in 4.19~rc1

  • Korean and Polish localization is not available (#18319). We will attempt to fix this in the final Tailss 4.19 release.

What's coming next?

Tails 4.19 will be the first release of a series of improvements to connect to Tor. Next, we will work on:

  • Saving Tor bridges to the Persistent Storage (#5461)
  • Detecting better when the computer has no supported Wi-Fi hardware (#14534)
  • Detecting captive portals (#5785)
  • Helping people fixing their clock when failing to connect to obfs4 bridges (#15548)

Happy testing!
