Im trying to install mysql and I get the error:

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

After some searching, I find this is perhaps giving access to debian-sys-maint, so I did this:

sudo cat /etc/mysql/debian.cnf

Then set the debian password in mysql:

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

Then I restart:

sudo /etc/init.d/mysql restart

And try and configure again:

sudo dpkg --configure -a

I get the same error.

A bit late but here it is: Firstly I'm on

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

I had to "uncheck" some software repositories. It can be easily done on Software & Updates GUI on the Other Software tab. I unchecked:

  • unstable repos
  • xenial repos
  • "disabled on upgrade to yakkety" repositories

The only checked repositories for me were:

software&updates window

Then, I solved the problem this way:

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

If the error(1819) is raised, type this on the mysql terminal

mysql> uninstall plugin validate_password;

Then restart mysql: systemctl restart mysql

Finally

apt install -f

to fix broken dependencies

If error continues, enter again to mysql terminal, login: type this:

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

apt -f install for the last time.

  • I can't believe that worked! :-D How did you figure that out? – Stack Underflow Feb 22 at 16:26
  • This worked for me on Ubuntu 16.04 – Stack Underflow Feb 22 at 16:36

This is coming after a lot of attempt at answering the question

Check the Users on the MYSQL installation

 mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;
 +-----------+-------------------------------------------+-----------------------+-----------+
 | User      | authentication_string                     | plugin                | Host      |
 +-----------+-------------------------------------------+-----------------------+-----------+
 | root      | *4C856331B587C990CC0D06E7EC93CB2D7A2CAD5F | mysql_native_password | localhost |
 | mysql     | invalid                                   | mysql_native_password | localhost |
 | wordpress | *2D2CF7300069DAB3433A5A0F49B92407769EBC56 | mysql_native_password | localhost |
 +-----------+-------------------------------------------+-----------------------+-----------+

Create the Debian-sys-maint User

 mysql> CREATE USER 'debian-sys-maint'@'localhost' IDENTIFIED BY 'password';

Use the same password in the debian.cnf file

user@system:~$ sudo cat /etc/mysql/debian.cnf

# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host     = localhost
user     = debian-sys-maint
password = **n4aSHUP04s1J32X5**
socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
user     = debian-sys-maint
password = **n4aSHUP04s1J32X5**
socket   = /var/run/mysqld/mysqld.sock
basedir  = /usr

mysql> CREATE USER 'debian-sys-maint'@'localhost' IDENTIFIED BY 'n4aSHUP04s1J32X5';

Grant the Debian-sys-maint user access

mysql> GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
mysql> EXIT
