出于各种原因，我正在尝试在本地计算机上重新安装mySQL。我在这里和堆栈上关注了服务器帖子。特别是详细关注了这篇文章，但是每次我完成这些步骤时，我都会以相同的结果结束。
Setting up mysql-client (5.7.20-0ubuntu0.16.04.1) ...
dpkg: dependency problems prevent configuration of mysql-server:
mysql-server depends on mysql-server-5.7; however:
Package mysql-server-5.7 is not configured yet.
dpkg: error processing package mysql-server (--configure):
dependency problems - leaving unconfigured
No apport report written because the error message indicates its a followup error from a previous failure.

在这一点上，我完全被难住了...
正如本文前面的讨论中所讨论的，我认为重新安装它是安全的。我们应该删除以前安装mysql的所有痕迹，然后重新安装它。
sudo apt-get remove --purge mysql*
如果这些是作为 mysql 的包依赖项的一部分安装的，
sudo apt-get autoremove
sudo apt-get autoclean
那么重要的一点是，此错误可能是因为您的发行版最近没有升级，或者至少冲突没有正确解决。我只会升级 Ubuntu。
sudo apt-get dist-upgrade
现在完成此操作后，您可以尝试再次正常安装mysql。希望这能奏效，请给报告。如果它不起作用，我们将尝试另一个修复程序。
这是mysql的数字海洋安装的链接。虽然你可以使用MariaDB。
