Still unable someway or somehow to install mysql8... had to remove all the files and folders created by webuzo for mysql - saving the backup of db's - then install mariaDB 10.3
Then I noticed Exim and PHP which showed as stoped and running respectibly where not actually installed... so... Webuzo also uninstall these programs/files - I had to reinstall both of then and now in a position of migration of DB's - someone in the Dev team Fck-it-up big time with these scripts...
