Here are the commands to run to import the MariaDB repository key on your Ubuntu system:

sudo apt-get install apt-transport-https curl
sudo mkdir -p /etc/apt/keyrings
sudo curl -o /etc/apt/keyrings/mariadb-keyring.pgp 'https://mariadb.org/mariadb_release_signing_key.pgp'

Once the key is imported, copy and paste the following into a file under /etc/apt/sources.list.d (for instance /etc/apt/sources.list.d/mariadb.sources):

# MariaDB 10.6 repository list - created 2023-07-13 06:43 UTC
# https://mariadb.org/download/
X-Repolib-Name: MariaDB
Types: deb
# deb.mariadb.org is a dynamic mirror if your preferred mirror goes offline. See https://mariadb.org/mirrorbits/ for details.
# URIs: https://deb.mariadb.org/10.6/ubuntu
URIs: https://ftp.heanet.ie/mirrors/mariadb/repo/10.6/ubuntu
Suites: jammy
Components: main main/debug
Signed-By: /etc/apt/keyrings/mariadb-keyring.pgp

You can now install MariaDB 10.6 from the MariaDB repository with:

sudo apt-get update
sudo apt-get install mariadb-server

Debug symbol packages, those that end in a ‘-dbgsym‘ suffix, are harmless to install. They are typically used to resolve stack traces and provide detail of perf recordings. They do not change the running behaviour of MariaDB. If in doubt, omit from installation.

If you need source packages, replace Types: deb with Types: deb deb-src in the /etc/apt/sources.list.d/mariadb.sources file. Then, you can obtain the mariadb source after installing dpkg-dev package, with apt-get source mariadb-server.

If you prefer to use the old “one-line-style” APT format, create the file /etc/apt/sources.list.d/mariadb.list with the following:

# MariaDB 10.6 repository list - created 2023-07-13 06:43 UTC
# https://mariadb.org/download/
# deb.mariadb.org is a dynamic mirror if your preferred mirror goes offline. See https://mariadb.org/mirrorbits/ for details.
# deb [signed-by=/etc/apt/keyrings/mariadb-keyring.pgp] https://deb.mariadb.org/10.6/ubuntu jammy main
deb [signed-by=/etc/apt/keyrings/mariadb-keyring.pgp] https://ftp.heanet.ie/mirrors/mariadb/repo/10.6/ubuntu jammy main
# deb-src [signed-by=/etc/apt/keyrings/mariadb-keyring.pgp] https://ftp.heanet.ie/mirrors/mariadb/repo/10.6/ubuntu jammy main

Here is your custom MariaDB DNF/YUM repository entry for CentOS. Copy and paste it into a file under /etc/yum.repos.d (we suggest naming the file MariaDB.repo or something similar).

# MariaDB 10.6 CentOS repository list - created 2023-07-13 06:44 UTC
# https://mariadb.org/download/
[mariadb]
name = MariaDB
# rpm.mariadb.org is a dynamic mirror if your preferred mirror goes offline. See https://mariadb.org/mirrorbits/ for details.
# baseurl = https://rpm.mariadb.org/10.6/centos/$releasever/$basearch
baseurl = https://ftp.heanet.ie/mirrors/mariadb/yum/10.6/centos/$releasever/$basearch
module_hotfixes = 1
# gpgkey = https://rpm.mariadb.org/RPM-GPG-KEY-MariaDB
gpgkey = https://ftp.heanet.ie/mirrors/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck = 1

EPEL repository may be required to satisfy the pv dependency of galera.

After the file is in place, install and start MariaDB with:

sudo yum install MariaDB-server MariaDB-client

If you haven’t already accepted the MariaDB GPG key, you will be prompted to do so during the install. See Installing MariaDB with yum for detailed information. Note the GPG was changed in January 2023 with more secure key. For more details see our blog article New GPG Release Key for RPMs.
