database - MariaDB 安装问题 'mariadb.service: Failed with result ' timeout'.'

Question

我正在尝试重新安装 MariaDB，但我不知道安装失败的原因。我之前安装了 MySQL，想用 MariaDB 来解决版本问题，所以如果你们能帮忙，谢谢。
这是我在 shell 上执行的一些命令和结果。
真的很抱歉我的shell是法语的，希望你们能帮助我。
之间，我有一个 Ubuntu 20.04tls 操作系统。

> sudo apt autoremove --purge ~n^mysql-server

> sudo apt install mariadb-server

它在安装菜单上失败:
在安装菜单上等待 2 或 3 分钟，然后显示: Job for mariadb.service failed because a timeout was exceeded. See "systemctl status mariadb.service" and "journalctl -xe" for details.
