Source: mariadb-10.1 Version: 10.1.21-5 Severity: serious As can be seen in the discussion for #852709, the source+amd64 upload for 10.1.21-5 did not include mariadb-plugin-tokudb, despite the package's architecture being base-any-any-amd64. Either a binNMU or a new source upload is needed (a test rebuild on barriere worked).
