我在 Google 上搜索了一段时间，但对于我在 VM 上遇到的这种奇怪情况，似乎没有什么明显的发现，有人可以帮帮我吗？

mariadb-server is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mariadb-client : Depends: mariadb-client-10.0 (= 10.0.20+maria-1~jessie) but 10.0.16-1 is to be installed
mariadb-server : Depends: mariadb-server-10.0 (= 10.0.20+maria-1~jessie) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

看来您已经安装了比存储库中可用的版本更新的 MariaDB 版本。您有 10.0.20，而存储库有 10.0.16-1。关于 MySQL 的通知是由于提供mariadb-client兼容性mysql-client包。
如果您确实想要从 repo 安装，则需要先卸载现有安装，然后从 repo 安装。
