Postinstall script referencing a wrong PATH for /usr/bin/mysql_install_db and better solutions suggestion

Details

    Description

      Hi,
      script referenced by postinstall script is wrong '/usr/scripts/scripts/mysql_install_db':
      mysqld_safe[25030]: The problem could be conflicting information in an external
      mysqld_safe[25030]: my.cnf files. You can ignore these by doing:
      mysqld_safe[25030]:
      mysqld_safe[25030]: shell> /usr/scripts/scripts/mysql_install_db --defaults-file=~/.my.cnf

      Should be '/usr/bin/mysql_install_db'.

      Error was originallly caused by an apparmor old mysqld profile (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865534) and:
      mysqld_safe[25030]: #007/usr/sbin/mysqld: Can't read dir of '/etc/mysql/mariadb.conf.d/' (Errcode: 13 "Permission denied")

      Question: is it possible/do we want to - have more intelligent postinstall script that could suggest better solutions?

          I read this but from the top of my head I don't have an approach to suggest.

          As suggestion from Michael Schaller seems relevant:
