Dangerzone is available for:

  • Ubuntu 22.10 (kinetic)
  • Ubuntu 22.04 (jammy)
  • Ubuntu 20.04 (focal)
  • Debian 12 (bookworm)
  • Debian 11 (bullseye)
  • Fedora 37
  • Fedora 36

Ubuntu, Debian

📝 Expand this section if you are on Ubuntu 20.04 (Focal).

Dangerzone requires Podman, which is not available through the official Ubuntu Focal repos. To proceed with the Dangerzone installation, you need to add an extra OpenSUSE repo that provides Podman to Ubuntu Focal users. You can follow the instructions below, which have been copied from the official Podman blog:

sudo apt-get install curl wget gnupg2 -y
source /etc/os-release
sudo sh -c "echo 'deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /' \
  > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list"
wget -nv https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_${VERSION_ID}/Release.key -O- \
  | sudo apt-key add -
sudo apt update

Also, you need to install the python-all package, due to an stdeb bug that existed before v0.9.1:

sudo apt-get install python-all -y

Add our repository following these instructions:

Download the GPG key for the repo:

gpg --keyserver hkps://keys.openpgp.org \
    --no-default-keyring --keyring ./fpf-apt-tools-archive-keyring.gpg \
    --recv-keys "DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281"
sudo mkdir -p /etc/apt/keyrings/
sudo mv fpf-apt-tools-archive-keyring.gpg /etc/apt/keyrings

Add the URL of the repo in your APT sources:

source /etc/os-release
echo deb [signed-by=/etc/apt/keyrings/fpf-apt-tools-archive-keyring.gpg] \
    https://packages.freedom.press/apt-tools-prod ${VERSION_CODENAME?} main \
    | sudo tee /etc/apt/sources.list.d/fpf-apt-tools.list

Install Dangerzone:

sudo apt update
sudo apt install -y dangerzone
📝 Expand this section for a security notice on third-party Debian repos

This section follows the official instructions on configuring third-party Debian repos.

To mitigate a class of attacks against our APT repo (e.g., injecting packages signed with an attacker key), we add an additional step in our instructions to verify the downloaded GPG key against its fingerprint.

Aside from these protections, the user needs to be aware that Debian packages run as root during the installation phase, so they need to place some trust on our signed Debian packages. This holds for any third-party Debian repo.

Fedora

Type the following commands in a terminal:

sudo dnf config-manager --add-repo=https://packages.freedom.press/yum-tools-prod/dangerzone/dangerzone.repo
sudo dnf install dangerzone
Importing GPG key 0x22604281: ... Is this ok [y/N]:

After some minutes of running the above command (depending on your internet speed) you'll be asked to confirm the fingerprint of our signing key. This is to make sure that in the case our servers are compromized your computer stays safe. It should look like this:

--------------------------------------------------------------------------------
Total                                           389 kB/s | 732 MB     32:07
Dangerzone repository                           3.8 MB/s | 3.8 kB     00:00
Importing GPG key 0x22604281:
 Userid     : "Dangerzone Release Key <dangerzone-release-key@freedom.press>"
 Fingerprint: DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281
 From       : /etc/pki/rpm-gpg/RPM-GPG-dangerzone.pub
Is this ok [y/N]:

Note: If it does not show this fingerprint confirmation or the fingerprint does not match, it is possible that our servers were compromized. Be distrustful and reach out to us.

The Fingerprint should be DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281. For extra security, you should confirm it matches the one at the bottom of our website (dangerzone.rocks) and our Mastodon account bio.

After confirming that it matches, type y (for yes) and the installation should proceed.
