我已经尝试过 "sudo apt-get clean" 和 "sudo apt-get install -f"，但仍然显示上面的信息。

运行 "sudo dpkg --configure -a" 会给我以下信息。

root@xxx:~# dpkg --configure -a
dpkg: dependency problems prevent configuration of mysql-server:
 mysql-server depends on mysql-server-5.5; however:
  Package mysql-server-5.5 is not installed.

dpkg: error processing package mysql-server (--configure):

你尝试过 # apt-get --install-recommends mysql-server mysql-server-5.5 吗？ - Ed de Almeida

你可能已经安装了 mariadb-server-10.1，但它拒绝降级。首先，运行 apt-get install dialog 命令，然后再次运行 apt-get install 命令，但不要带上 -y 标志。 - Kenney

我的问题是我已经用完了磁盘空间，但没有注意到。 - aggregate1166877

我也遇到了这个错误。浪费了很多时间后，我找到了这个链接 https://cursos.alura.com.br/forum/topico-erro-de-dependencia-ao-instalar-mysql-server-83591 - Muhammad Faizan Fareed

我曾经遇到同样的问题。这个教程帮助我解决了我的问题：Package mysql-server-5.5 is not configured yet

sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean

完全卸载mysql后，请运行以下命令

sudo apt-get dist-upgrade

然后重新安装MySQL

sudo apt-get install mysql-server
