用户'debian-sys-maint'的访问被拒绝-安装mysql吗？

我试图安装mysql，但出现错误：

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带来麻烦，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';

然后我重新启动：

sudo /etc/init.d/mysql restart

并再次尝试配置：

sudo dpkg --configure -a

我犯了同样的错误。

有点晚了，但是在这里：首先我在

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

我不得不“取消选中”某些软件存储库。可以Software & Updates在Other Software选项卡上的GUI上轻松完成。我未选中：

• 不稳定的仓库
• 塞纳回购
• “在升级到yakkety时禁用”存储库

对我来说，唯一检查过的存储库是：

软件和更新窗口

然后，我以这种方式解决了这个问题：

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

如果出现错误（1819），请在mysql终端上键入

mysql> uninstall plugin validate_password;

然后重启mysql： systemctl restart mysql

最后

apt install -f

修复损坏的依赖项

如果错误仍然存​​在，请再次输入mysql终端，登录：键入：

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

apt -f install 最后一次。
