GPG
Information about the GPG keys used to sign MariaDB packages and repositories, including how to import them for verification.
The MariaDB project signs their MariaDB packages for Debian, Ubuntu, Fedora, and Red Hat. This page documents information about the keys that we use and have used.
MariaDB Community Server Debian / Ubuntu key
Our MariaDB Community Server repositories for Debian "Sid" and the Ubuntu 16.04 and beyond "Xenial" use the following GPG signing key. As detailed in MDEV-9781, APT 1.2.7 (and later) prefers SHA2 GPG keys and now prints warnings when a repository is signed using a SHA1 key like our previous GPG key. We have created a SHA2 key for use with these.
Information about this key:
The short Key ID is:
0xC74CD1D8The long Key ID is:
0xF1656F24C74CD1D8The full fingerprint of the key is:
177F 4010 FE56 CA33 3630 0305 F165 6F24 C74C D1D8The key can be added on Debian-based systems using the following command:
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8Usage of the
apt-keycommand is deprecated in the latest versions of Debian and Ubuntu, and the replacement method is to download the keyring file to the/etc/apt/trusted.gpg.d/directory. This can be done with the following:
sudo curl -LsSo /etc/apt/trusted.gpg.d/mariadb-keyring-2019.gpg https://supplychain.mariadb.com/mariadb-keyring-2019.gpgMariaDB Community Server RPM / Source Keys
Beginning in 2023 we migrated the key used to sign our yum/dnf/zypper repositories and to sign our source code and binary tarballs to the same key we use for Debian and Ubuntu.
Key ID and Fingerprint information is in the MariaDB Community Server Debian/Ubuntu Key section, above.
The key can be imported on RPM-based systems using the following command:
sudo rpm --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEYor
sudo rpmkeys --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEYThe GPG Key ID of the MariaDB signing key we used for yum/dnf/zypper repositories and to sign our source code tarballs until the end of 2022 was 0xCBCB082A1BB943DB. The short form of the id is 0x1BB943DB and the full key fingerprint is:
1993 69E5 404B D5FC 7D2F E43B CBCB 082A 1BB9 43DBThis key was used by the yum/dnf/zypper repositories for RedHat, CentOS, Fedora, openSUSE, and SLES.
If you configure the mariadb.org rpm repositories using the repository configuration tool then your package manager will prompt you to import the key the first time you install a package from the repository.
You can also import the key directly using the following command:
sudo rpmkeys --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEY-2010MariaDB Enterprise GPG Keys

For RHEL, AlmaLinux, Rocky, and Oracle Linux 10 and above, and for Debian 13 Trixie and above there are new requirements around GPG keys used to sign rpm packages. For these distributions we have created a stronger GPG key for our Enterprise Server releases.
