Search for mail_plugins and make the following changes on that line

Apr 29 03:09:02 sd-71796 postfix/master[43779]: fatal: bind 0.0.0.0 port 25: Address already in use
So, looks like we have the port 25 in use!
service sendmail stop
service postfix restart
service sendmail start
After doing this the /var/mail/ had the user’s files!
Send a test email
mail -s "Test Subject" [email protected] < /dev/null
To set up an user you need to Configure Additional Email Addresses.

Original solution from http://www.dbrnd.com/2015/08/reset-mysql-root-password-ubuntu/
Here is a good tutorial how to do it.
Lets simply force mysqldump to ignore all performance_schema tables.
# mysqldump -u <username> -p <password> --all-databases > /root/mysql.full.dump --ignore-table=performance_schema.cond_instances --ignore-table=performance_schema.events_waits_current --ignore-table=performance_schema.cond_instances --ignore-table=performance_schema.events_waits_history --ignore-table=performance_schema.events_waits_history_long --ignore-table=performance_schema.events_waits_summary_by_instance --ignore-table=performance_schema.events_waits_summary_by_thread_by_event_name --ignore-table=performance_schema.events_waits_summary_global_by_event_name --ignore-table=performance_schema.file_instances --ignore-table=performance_schema.file_summary_by_event_name --ignore-table=performance_schema.file_summary_by_instance --ignore-table=performance_schema.mutex_instances --ignore-table=performance_schema.performance_timers --ignore-table=performance_schema.rwlock_instances --ignore-table=performance_schema.setup_consumers --ignore-table=performance_schema.setup_instruments --ignore-table=performance_schema.setup_timers --ignore-table=performance_schema.threads
But remember!
An error is always an error!
This solution isn’t 100% recommended!
root@colo18:~# mysqldump -u root --all-databases > colo18.sql mysqldump: Couldn't execute 'show fields from `crongal`': Can't create/write to file '/tmp/#sql_b8c_0.MYI' (Errcode: 13) (1)
Lets set the proper permissions to /temp
sudo chmod 1777 /tmpIt will solve the issue.
