How to install Tails on USB flash drive or SD card

Why Tails is not only for hacktivists and whistleblowers and how to get started

Requirements

  • USB flash drive or SD card (faster is better)
  • Computer running macOS Big Sur or Monterey or Debian-based operating system

Caveats

  • When copy/pasting commands that start with $, strip out $ as this character is not part of the command

Guide (macOS)

Step 1: install Homebrew

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

$ uname -m | grep arm64 && echo 'export PATH=$PATH:/opt/homebrew/bin' >> ~/.zshrc && source ~/.zshrc

Step 2: disable Homebrew analytics

brew analytics off

Step 3: install GnuPG

brew install gnupg

Step 4: import “Tails developers” PGP public key

$ curl https://tails.boum.org/tails-signing.key | gpg --import

Step 5: download Tails release

Go to https://tails.boum.org/install/download/index.en.html and download latest release and associated PGP signature (found under “or download the OpenPGP signature”) to ~/Downloads folder.

Step 6: verify Tails release (learn how here)

Heads-up: replace 4.29 with latest release semver.

$ gpg --verify ~/Downloads/tails-amd64-4.29.img.sig
gpg: assuming signed data in '/Users/sunknudsen/Downloads/tails-amd64-4.29.img'
gpg: Signature made Mon  4 Apr 08:10:52 2022 EDT
gpg:                using RSA key 753F901377A309F2731FA33F7BFBD2B902EE13D0
gpg: Good signature from "Tails developers (offline long-term identity key) <tails@boum.org>" [unknown]
gpg:                 aka "Tails developers <tails@boum.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: A490 D0F4 D311 A415 3E2B  B7CA DBB8 02B2 58AC D84F
     Subkey fingerprint: 753F 9013 77A3 09F2 731F  A33F 7BFB D2B9 02EE 13D0

Good signature

Step 7: copy Tails to USB flash drive or SD card

WARNING: BE VERY CAREFUL WHEN RUNNING DD AS DATA CAN BE PERMANENTLY DESTROYED (BEGINNERS SHOULD CONSIDER USING BALENAETCHER INSTEAD).

Heads-up: run diskutil list to find disk ID of USB flash drive or SD card to overwrite with Tails (disk4 in the following example).

Heads-up: replace diskn and rdiskn with disk ID of USB flash drive or SD card (disk4 and rdisk4 in the following example) and tails-amd64-4.29.img with current image.

$ diskutil list
/dev/disk0 (internal):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

/dev/disk3 (synthesized):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   6:                APFS Volume VM                      2.1 GB     disk3s6

/dev/disk4 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *32.1 GB    disk4
   1:               Windows_NTFS Untitled                32.1 GB    disk4s1

$ sudo diskutil unmount /dev/diskn
disk4 was already unmounted or it has a partitioning scheme so use "diskutil unmountDisk" instead

$ sudo diskutil unmountDisk /dev/diskn (if previous step fails)
Unmount of all volumes on disk4 was successful

$ sudo dd bs=1m if=$HOME/Downloads/tails-amd64-4.29.img of=/dev/rdiskn

$ sudo diskutil unmountDisk /dev/diskn
Unmount of all volumes on disk4 was successful

$ sudo apt update

$ sudo apt install curl gnupg

Step 2: import “Tails developers” PGP public key

$ curl https://tails.boum.org/tails-signing.key | gpg --import

Step 3: set Tails release semver environment variable

Heads-up: replace 4.29 with latest release semver.

TAILS_RELEASE_SEMVER=4.29

Step 4: download Tails release

$ curl --fail --location --remote-name https://mirrors.edge.kernel.org/tails/stable/tails-amd64-${TAILS_RELEASE_SEMVER}/tails-amd64-${TAILS_RELEASE_SEMVER}.img

$ curl --fail --location --remote-name https://tails.boum.org/torrents/files/tails-amd64-${TAILS_RELEASE_SEMVER}.img.sig

Step 5: verify Tails release (learn how here)

$ gpg --verify tails-amd64-${TAILS_RELEASE_SEMVER}.img.sig
gpg: assuming signed data in 'tails-amd64-4.29.img'
gpg: Signature made Mon 04 Apr 2022 08:10:52 AM EDT
gpg:                using RSA key 753F901377A309F2731FA33F7BFBD2B902EE13D0
gpg: Good signature from "Tails developers (offline long-term identity key) <tails@boum.org>" [unknown]
gpg:                 aka "Tails developers <tails@boum.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: A490 D0F4 D311 A415 3E2B  B7CA DBB8 02B2 58AC D84F
     Subkey fingerprint: 753F 9013 77A3 09F2 731F  A33F 7BFB D2B9 02EE 13D0

Good signature

Step 6: copy Tails to USB flash drive or SD card

WARNING: BE VERY CAREFUL WHEN RUNNING DD AS DATA CAN BE PERMANENTLY DESTROYED (BEGINNERS SHOULD CONSIDER USING BALENAETCHER INSTEAD).

Heads-up: run sudo fdisk --list to find device name of USB flash drive or SD card to overwrite with Tails (sda in the following example).

Heads-up: replace sdn with device name of USB flash drive or SD card (sda in the following example).
