Linux Mint and XAMPP: not loading my.cnf file changes

I am trying to set innodb_log_file_size and max_allowed_packet values on my mysql. I am using xampp under Linux Mint 20. So I edited /etc/mysql/my.cnf The file looks like: # # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location. # Here is entries for some specific programs # The following values assume you have at least 32M ram [mysqld] innodb_log_file_size=256M max_allowed_packet=256M I finally restarted mysql with: sudo /opt/lampp/lampp restart But I am not getting the new values if I execute SHOW VARIABLES LIKE 'max_allowed_packet' on my mysql. What am I missing?
