Error mysql dump using Workbench, or Navicat

Good morning ..

I have a small vps in debian 9, i-mscp 1.5.1 with maria db 10.2 I'm going to move some
things, after moving a database trying to make a remote copy and get the
following error ... although the copy is completed

I have made the suggested action for this type of error

mysql_upgrade -u root -h localhost -p --verbose --force

Restarted the vps

But when I go back down any database the error is the same always

mysqldump:
Could not execute 'show events': Can not proceed because system tables
used by Event Scheduler were found damaged at server start (1577)

Operation failed with exitcode 2

Someone of you has appreciated this problem and if you have solved it, you can tell me some clue or url to correct it

Thank you

Hey Nuxwin good day for you ..., I have executed this option that you inform me, but still
giving error, I in version 10.1 and I attached parameter to the
configuration

event_scheduler = ON

And it works correctly but in 10.2, that option is ignored, using navicatm workbech, heidisql ...

I try to define the default parameter, but I do not get a result

global set event_scheduler = ON;
ERROR
1290 (HY000): The MariaDB server is rolling with the option
--event-scheduler = DISABLED or --skip-grant-tables such that it can not
execute this command
and I can not activate the variable

Any advice for this is good, another solution is to download mariadb to version 10.1, but I think it's better to look forward

Thank you
