A similar error appeared in MySQL Workbench 8.0.21 after installing XAMPP 7.4.8 on Ubuntu 18.04. There were no problems using phpMyAdmin.

Error Code: 1558 Column count of mysql.proc is wrong. Expected 21, found 20. Created with MariaDB 100108, now running 100413. Please use mysql_upgrade to fix this error

Solution:

sudo /opt/lampp/lampp start
/opt/lampp/bin/mysql_upgrade

I had this error as well. I fixed it by running

mysql_upgrade -u root -p

Also, restart the mysql service by running

service mysqld restart

Answer 4

I had the same problem when I updated XAMPP from xampp-osx-7.2.10 to 7.3.9 in MacOS Mohave. So the solution was:

Find the file mysql_upgrade in "Macintosh HD⁩ ▸ ⁨Applications⁩ ▸ ⁨XAMPP⁩ ▸ ⁨xamppfiles⁩ ▸ ⁨bin⁩" and double click on it.

Answer 5

This error happens when a bad upgrade is done. For example, it happens if you upgrade from 5.0 to 5.1 but don't run the mysql_upgrade script; or, in rare cases, it probably happens if you directly upgrade from 5.0 to 5.5. (Many people does this, but such updrages are not officially supported) You say you are using a hosting service - well, I think that you should create a ticket and tell them about the problem. If you don't have the SUPER privilege, there is nothing you can do. But if you have that right, simply run mysql_upgrade: http://dev.mysql.com/doc/refman/5.1/en/mysql-upgrade.html

Answer 6

I had the same problem when I updated the mysql server from 5.5 to 5.7 in Debian 8 (jessie). In my case, it worked fine when I executed the follow command:

mysql_upgrade --force -uroot -p

Hope it will help you
