By default, Debian 12 installs MariaDB version 10.x, and some applications require a newer version. This guide describes the process of upgrading to MariaDB version 11.3.

1. Add the repository

/etc/apt/sources.list.d/
apt install curl
curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version="mariadb-11.3"

2. Update installed packages

apt update
apt upgrade
systemctl stop mariadb
apt install --only-upgrade mariadb-server
apt autoremove
systemctl daemon-reload
systemctl start mariadb

2.1 In case of a startup error, comment out the lines in the configuration

/etc/mysql/mariadb.conf.d/

provider_bzip2.cnf
#provider_bzip2=force_plus_permanent

provider_lz4.cnf
#provider_lz4=force_plus_permanent

provider_lzma.cnf
#provider_lzma=force_plus_permanent

provider_lzo.cnf
#provider_lzo=force_plus_permanent

provider_snappy.cnf
#provider_snappy=force_plus_permanent

3. Database upgrade

service mariadb restart
mariadb-upgrade

If necessary, using a password:

mariadb-upgrade -u root -p

Done! To check the version, you can use the command:

dpkg -l | grep mariadb

or

mariadb
