I put the root password with debconf dialogue, but it shows an error:

> Unable to set password for the Percona Server "root" user
>
> An error occurred while setting the password for the Percona Server administrative user. This may have happened because the account already has a password, or because of a
> communication problem with the Percona Server daemon.

> You should check the account's password after the package installation.

Installed mysqld can be accessed without password.

$ mysql -u root
