To solve a mysqldump "Workbench was unable to get mysqldump version. Please verify the log for more information.", I opted for the first solution at


But now workbench does not throw a error, so I check the error log.

14:32:30 [ERR][SqlEditorSchemaTree]: Exception querying metadata from mysql.proc, will fallback to SHOW PROCEDURE: Exception: Table 'mysql.proc' doesn't exist
14:32:31 [INF][wb_admin_control.py:query_server_info:714]: WbAdminControl.connect_sql(): The server version stored in the server instance profile was "5.7.25-0ubuntu0.18.04.2". Changed to the version reported by the server: "8.0.15"

select version(), WB Server Status, mysqld, and mysqldump returns 8.0.15 . So before I start to further debugging, I was wondering if anybody knows what else may have let to my server instance profiled be populated with the wrong MySQL version. I had previously uninstalled this version and upgrade to MySQL 8. When I do which on mysqld and mysqldump, I only get 1 instance of each.

Here is my config:

MySQL Workbench Community (GPL) for Linux/Unix version 6.3.8 CE build 1228 (64 bit)
Configuration Directory: /home/ras-pc/.mysql/workbench
Data Directory: /usr/share/mysql-workbench
Cairo Version: 1.15.10
OS: Linux 4.15.0-46-generic
CPU: 4x Intel(R) Core(TM) i5-4590T CPU @ 2.00GHz (1970.580MHz) - 7.70GiB RAM
Distribution: Ubuntu 18.04.1 LTS

Checking my installation logs on 5 of March, I found

and on 6th of Mar, the server seems to be running properly.

So I presume everything is fine from the installation standpoint. I have been using the database every work day since then.

  • Welcome to the site, Are you sure , you have been successfully installed the MySQL version 8? – Md Haidar Ali Khan Mar 18 at 7:40
  • Updated question with installation logs. I cannot be 100% sure the installation was successful. It failed, but on the next day, it appears mysql-community-server started properly. I have been using MySQL with triggers, import and export databases without any issue. Only issue is with 'data export', I have to use mysqldump command line. – sunyata Mar 18 at 8:41

    I cannot be 100% sure the installation was successful. It failed, but on the next day This means your MySQL instance is (partially) damaged. Why you are surprised that some operations cannot be performed on a broken instance? – Akina Mar 18 at 9:09
  • This problem mysteriously went away. – sunyata Apr 10 at 6:39
