For more details, read our changelog.
- Automatic upgrades are broken from Tails 4.14 and earlier.
To upgrade from Tails 4.14 or earlier, you can either:
- Do a manual upgrade.
- Fix the automatic upgrade from a terminal. To do so:
- Start Tails and set up an administration password.
- In a terminal, execute the following command:
torsocks curl --silent https://gitlab.tails.boum.org/tails/tails/-/raw/master/config/chroot_local-includes/usr/share/tails/certs/lets-encrypt-r3.pem \ | sudo tee --append /usr/local/etc/ssl/certs/tails.boum.org-CA.pem \ && systemctl --user restart tails-upgrade-frontend
This command is a single command that wraps across several lines. Copy and paste the entire block at once and make sure that it executes as a single command.
- About 30 seconds later, you should be prompted to upgrade to the latest version of Tails. If no prompt appear, you might already be running the latest version of Tails.
See the list of long-standing issues.
- Automatic upgrades are broken from Tails 4.14 and earlier. See the known issue above.
- Automatic upgrades are available from Tails 4.15 or later to 4.16.
- If you cannot do an automatic upgrade or if Tails fails to start after an automatic upgrade, please try to do a manual upgrade.
Follow our installation instructions:
The Persistent Storage on the USB stick will be lost if you install instead of upgrading.
If you don’t need installation or upgrade instructions, you can download Tails 4.16 directly:
Tails 4.17 is scheduled for March 23.
