我已经从 Ubuntu 16.04 LTS 32 位迁移到 18.04 LTS。
由于 18.04 安装了 Mariadb 10.1.48，已将以下 Mariadb 10.2 存储库添加到 /etc/apt/sources.list ，更新后以下内容显示为候选，
# apt-cache policy mariadb-server
mariadb-server:

当尝试安装 mariadb-client 和 mariadb-server 时，我出现以下错误。
# apt install -f mariadb-server

我安装了 mariadb 10.2.2 xenial 版本，并尝试升级，但徒劳无功。甚至尝试寻找旧的 i386 deb 包。
安装 xenial 源时，我能够安装 mariadb-10.2，但它无法运行。
任何有关在 32 位 bionic 上运行 Mariadb 10.2.2 或更高版本的帮助都将不胜感激。
谢谢，
