*nix package repositories

You can easily add Puppet’s package repositories to a *nix operating system by downloading and installing a compatible package.

Yum-based systems

For Red Hat Enterprise Linux and its derivatives:

To enable the repository, run the command below that corresponds to your OS version:

Enterprise Linux 7

$ sudo rpm -ivh https://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm

Enterprise Linux 6

$ sudo rpm -ivh https://yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm

Enterprise Linux 5

$ sudo rpm -ivh https://yum.puppetlabs.com/puppetlabs-release-el-5.noarch.rpm

For Fedora:

To enable the repository, run the command below that corresponds to your OS version:

Fedora 20

$ sudo rpm -ivh https://yum.puppetlabs.com/puppetlabs-release-fedora-20.noarch.rpm

Apt-based systems

For Ubuntu and Debian:

To enable the repository:

1. Download the “puppetlabs-release” package for your OS version.
   • You can see a full list of these packages on the front page of https://apt.puppetlabs.com/. They are all named puppetlabs-release-<CODE NAME>.deb. (For Ubuntu releases, the code name is the adjective, not the animal.)
   • Architecture is handled automatically; there is only one package per OS version.
2. Install the package by running dpkg -i <PACKAGE NAME>.
3. Run apt-get update to get the new list of available packages.

For example, to enable the repository for Ubuntu 12.04 Precise Pangolin:

wget https://apt.puppetlabs.com/puppetlabs-release-precise.deb
sudo dpkg -i puppetlabs-release-precise.deb
sudo apt-get update

To enable the repository for Ubuntu 14.04 Trusty Tahr:

wget https://apt.puppetlabs.com/puppetlabs-release-trusty.deb
sudo dpkg -i puppetlabs-release-trusty.deb
sudo apt-get update

OS X and Windows systems

You can download installable packages from downloads.puppetlabs.com for Puppet agent software on OS X and Windows. For more information, see the OS X and Windows installation instructions.

Verifying Puppet packages

At Puppet, we sign most of our packages, Ruby gems, and release tarballs with GNU Privacy Guard (GPG). This helps prove that the packages originate from Puppet and have not been compromised.

Security-conscious users can use GPG to verify signatures on our packages.

Automatic verification

Certain operating system and installation methods automatically verify our package signatures.

• If you install Puppet packages via our Yum and Apt repositories, the Puppet release package that enables the repository also installs our release signing key. The Yum and Apt tools automatically verify the integrity of our packages as you install them.
• Our Microsoft Installer (MSI) packages for Windows are signed with a different key, and the Windows installer automatically verifies the signature before installing the package.

In these cases, you don’t need to do anything to verify the package signature.

Manual verification

If you’re using Puppet source tarballs or Ruby gems, or installing RPM packages without Yum, you can manually verify the signatures.

Import the release signing key

Before you can verify signatures, you must import the Puppet public key and verify its fingerprint. This key is certified by several Puppet developers and should be available from the public keyservers.

To import the release signing key, run:

gpg --recv-key 1054b7a24bd6ec30

The gpg tool then requests and imports the key:

gpg: requesting key 4BD6EC30 from hkp server keys.gnupg.net
gpg: /home/username/.gnupg/trustdb.gpg: trustdb created
gpg: key 4BD6EC30: public key "Puppet Labs Release Key (Puppet Labs Release Key) <info@puppetlabs.com>" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

The key is also available via HTTP.

Note: If this is your first time running the gpg tool, it might fail to import the key after creating its configuration file and keyring. This is normal, and you can run the command a second time to import the key into your newly created keyring.

Verify the fingerprint

The fingerprint of the Puppet release signing key is 47B3 20EB 4C7C 375A A9DA E1A0 1054 B7A2 4BD6 EC30. Run the following:

gpg --list-key --fingerprint 1054b7a24bd6ec30

Then, ensure the fingerprint listed in the output matches the above value:

pub   4096R/4BD6EC30 2010-07-10 [expires: 2016-07-08]
      Key fingerprint = 47B3 20EB 4C7C 375A A9DA  E1A0 1054 B7A2 4BD6 EC30
uid                  Puppet Labs Release Key (Puppet Labs Release Key) <info@puppetlabs.com>

Verify a source tarball or gem

To verify a source tarball or Ruby gem, you must download both it and its corresponding .asc file. These files are available from https://downloads.puppetlabs.com/puppet/.

Next, verify the tarball or gem by running the following, replacing <VERSION> with the Puppet version number, and <FILE TYPE> with tar.gz for a tarball or gem for a Ruby gem:

gpg --verify puppet-<VERSION>.<FILE TYPE>.asc puppet-<VERSION>.<FILE TYPE>

The output should confirm that the signature matches:

gpg: Signature made Mon Nov 30 10:47:39 2015 PST using RSA key ID 4BD6EC30
gpg: Good signature from "Puppet Labs Release Key (Puppet Labs Release Key) <info@puppetlabs.com>"

If you have not taken the necessary steps to build a trust path, through the web of trust, to one of the signatures on the release key, gpg produces a warning similar to the following when you verify the signature:

Could not find a valid trust path to the key.
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: 47B3 20EB 4C7C 375A A9DA  E1A0 1054 B7A2 4BD6 EC30

This is normal if you do not have a trust path to the key. If you’ve verified the fingerprint of the key as described above, GPG has verified the archive’s integrity; the warning only means that GPG can’t automatically prove the key’s ownership.

Verify an RPM package

Puppet RPM packages include an embedded signature. To verify it, you must import the Puppet public key to rpm, then use rpm to check the signature.

First, retrieve the Puppet public key and place it in a file on your node.

Next, run the following, replacing <PUBLIC KEY FILE> with the path to the file containing the Puppet public key:

sudo rpm --import PUBKEY <PUBLIC KEY FILE>

The rpm tool won’t output anything if successful.

Then to verify an RPM you’ve downloaded, run the rpm tool with the checksig flag (-K):

sudo rpm -vK <RPM FILE NAME>

This verifies the embedded signature, as signified by the OK results in the rpm output:

puppetlabs-release-el-7.noarch.rpm:
    Header V4 RSA/SHA1 Signature, key ID 4bd6ec30: OK
    Header SHA1 digest: OK (56f61c254f780d67d01e2d685d4dad2be9decafb)
    V4 RSA/SHA1 Signature, key ID 4bd6ec30: OK
    MD5 digest: OK (6c7d3948cdecdeccb8e4f24947ad4d20)

If you don’t import the Puppet public key, you can still verify the package’s integrity using rpm -vK. However, you won’t be able to validate the package’s origin:

puppetlabs-release-el-7.noarch.rpm:
    Header V4 RSA/SHA1 Signature, key ID 4bd6ec30: NOKEY
    Header SHA1 digest: OK (56f61c254f780d67d01e2d685d4dad2be9decafb)
    V4 RSA/SHA1 Signature, key ID 4bd6ec30: NOKEY
    MD5 digest: OK (6c7d3948cdecdeccb8e4f24947ad4d20)

#### Verify an OS X installer

Puppet signs OS X installation packages with a developer ID and certificate. To verify the signature, download and mount the disk image, then use the `pkgutil` tool with the `--check-signature` flag:

    pkgutil --check-signature /Volumes/puppet-3.8.7/puppet-3.8.7.pkg

The tool confirms the signature and outputs fingerprints for each certificate in the chain:

Package “puppet-3.8.7.pkg”: Status: signed by a certificate trusted by Mac OS X Certificate Chain: 1. Developer ID Installer: PUPPET LABS, INC. (VKGLGN2B6Y) SHA1 fingerprint: AF 91 BF B7 7E CF 87 9F A8 0A 06 C3 03 5A B4 C7 11 34 0A 6F —————————————————————————– 2. Developer ID Certification Authority SHA1 fingerprint: 3B 16 6C 3B 7D C4 B7 51 C9 FE 2A FA B9 13 56 41 E3 88 E1 86 —————————————————————————– 3. Apple Root CA SHA1 fingerprint: 61 1E 5B 66 2C 59 3A 08 FF 58 D1 4A E2 24 52 D1 98 DF 6C 60 ```

You can also confirm the certificate when installing the package by clicking the lock icon in the top-right corner of the installer:
