On Ubuntu and Debian, as part of the upgrade to Galera version 25.3.9, the Galera Arbitrator daemon (garbd) and the galera library have been renamed and split into separate packages. The packages are named galera-3 and galera-arbitrator-3. When installing MariaDB Galera Cluster on Ubuntu and Debian (the mariadb-galera-server package), the galera-3 package will be automatically installed. You can then install the arbitrator package on a separate node (recommended) or on one of the nodes running mariadb-galera-server (not recommended).

Running MariaDB Galera Cluster 5.5 and 10.0 nodes in a cluster is not supported ()
This version of MariaDB Galera Cluster supports wsrep API v25 which means MariaDB Galera Cluster can be used with either a 25.2.x or 25.3.x Galera wsrep provider. A 25.3.x wsrep provider is included in the MariaDB repositories and is also available from the page.

Note: If Galera 25.2.x and 25.3.x are both being used in the cluster, MariaDB with Galera 25.3.x must be started with in order to make it backward compatible with Galera v2. Galera wsrep providers other than 25.3.x or 25.2.x are not supported.

Thanks, and enjoy MariaDB Galera Cluster!
