Description:
----[For better reports, please attach the log file after submitting. You can find it in /home/lucas/.mysql/workbench/log/wb.log]

How to repeat:
Cannot Connect to Database Server
Your connection attempt failed for user 'root' from your host to server at localhost:3306:
  Native table 'performance_schema'.'session_variables' has the wrong structure

Please:
1 Check that mysql is running on server localhost
2 Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
3 Check the root has rights to connect to localhost from your address (mysql rights define what clients can connect to the server and from which machines) 
4 Make sure you are both providing a password if needed and using the correct password for localhost connecting from the host address you're connecting from

Suggested fix:
Manda uma release para mim conseguir restaurar !
