16.04 – 用户’debian-sys-maint’拒绝访问 – 安装mysql？

我试图安装mysql,我得到错误：

mysql_upgrade: Got error: 1045: Access denied for user 'debian-sys-maint'@'localhost' (using password: YES) while connecting to the MySQL server

经过一番搜索后,我发现这可能会给debian-sys-maint提供一些帮助,所以我：

sudo cat /etc/mysql/debian.cnf

然后在mysql中设置debian密码：

mysql -u root -p <password>
GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY 'password-here';

然后我重启：

sudo /etc/init.d/mysql restart

然后再次尝试配置：

sudo dpkg --configure -a

我犯了同样的错误.

解决方法:

有点晚了但是这里是：
首先我在

Distributor ID: Ubuntu
Description:    Ubuntu 16.10
Release:    16.10
Codename:   yakkety

我不得不“取消选中”一些软件存储库.它可以很容易地在Software&更新“其他软件”选项卡上的GUI.我取消选中：

>不稳定的回购
> xenial回购
>“升级到yakkety时禁用”存储库

我唯一检查的存储库是：

software&updates window

然后,我这样解决了问题：

sudo su

root@iqbal: mysql -u root -p
Enter password:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY '<your password>';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

如果引发错误(1819),请在mysql终端上键入this

mysql> uninstall plugin validate_password;

然后重启mysql：systemctl重启mysql

最后

apt install -f

修复破坏的依赖项

如果错误仍然存​​在,请再次输入mysql终端,登录：
输入：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY '<your password>'

apt -f最后一次安装.
