Rotating keys
For security reasons, the keys used to sign Centreon RPMs or the Debian repository must be rotated occasionally.
Fresh installation
- Alma/RHEL/Oracle Linux
- Debian
If you performed a fresh installation after the new RPM key was published, no additional actions are necessary, apart from accepting the new rpm key.
Retrieving key from https://yum-gpg.centreon.com/RPM-GPG-KEY-CES
Importing GPG key 0x3FC49C1B:
Userid : "Centreon Enterprise Server Official Signing Key <admin@centreon.com>"
Fingerprint: 1035 e42c b766 7952 ee42 dee9 a97d aa5a 3fc4 9c1b
From : https://yum-gpg.centreon.com/RPM-GPG-KEY-CES
Is this ok [y/N]:
If you performed a fresh installation after the new key was published, no additional actions are necessary.
However, you can check that you have the correct key.
Existing installation
- Alma/RHEL/Oracle Linux
- Debian
If you performed a fresh installation of a Centreon platform before the new RPM key was published, the existing key must be replaced with the new one.
Download the following script:
curl -JO https://raw.githubusercontent.com/centreon/centreon/master/centreon/check-centreon-gpg-key.sh
Make the script executable:
chmod u+x check-centreon-gpg-key.sh
Run the script:
sh check-centreon-gpg-key.sh
The script will:
- check the RPM key in the RPM database and ask you to remove it
- check the key file in the /etc/pki/rpm-gpg directory
- ask you to fetch and import the new RPM key into the RPM database
- ask you to update the release RPM package (this will remove the revoked key from /etc/pki/rpm-gpg)
- ask you to check the signature of the RPM packages.
Remove the old key:
apt-key del 1441882BED29D70CF2E874D65E9C374559B6C02E
Import the new key:
wget -O- https://apt-key.centreon.com | gpg --dearmor | tee /etc/apt/trusted.gpg.d/centreon.gpg > /dev/null 2>&1
apt update
Checks
- Alma/RHEL/Oracle Linux
- Debian
You can then check that the new key has been correctly imported. For the new key published on October 14, 2021:
- Fresh installation
- Existing installation
After installation, check if the new key has been correctly imported into the RPM database:
rpm -qi gpg-pubkey-3fc49c1b-651d4c25
