我最近问了一个问题这个帖子
我得到了一些帮助，但我的问题没有得到解决。我仍然无法访问 phpmyadmin，mysql 也无法正常运行。这就是我现在的情况。
我运行了这个代码：
$ systemctl status mysql.service
● mysql.service - MySQL Community Server
Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
Active: activating (start-post) (Result: exit-code) since Tue 2017-01-10 09:17:03 CST; 16s ago

我之前尝试过卸载并重新安装所有内容。这个过程如下：
logan@logan-Latitude-E6320:~$ sudo rm -f /var/lib/mysql/debian-*.flag
logan@logan-Latitude-E6320:~$ sudo apt-get install -f

我认为该问题出在 /usr/bin/dpkg（因为它返回了错误代码，但我不知道如何解决该问题。有人知道要采取什么步骤才能解决问题吗？
欢迎任何建议，我提前感谢您的帮助。
如果您需要任何更多信息，请告诉我。
编辑 1：此问题已被确定为另一个问题的可能重复。那个可能的重复是我之前问过的问题，但并未给出问题的解决方案。

我不确定你做了什么，如果你更改了 mysql 密码，你需要更改 phpadmin 存储在文件“config.inc.php”中的访问 PHP 的密码。
您可以在这里阅读一些内容。如何更改 mysql 和 phpmyadmin 的 root 密码
