Hello! Thanks for taking the time to write a good bug report and investigate the situation. Indeed, mysql_upgrade is at the moment shipped in the mariadb-server-10.0 package and triggered from its postinstall scripts and in certain situations from the init script (the debian-start is called from the init script):
mariadb-10.0/debian$ grep -R mysql_upgrade *additions/debian-start:MYUPGRADE="/usr/bin/mysql_upgrade --defaults-extra-file=/etc/mysql/debian.cnf" additions/mariadb.conf.d/50-mysql-clients.cnf:[mysql_upgrade] mariadb-server-10.0.install:usr/bin/mysql_upgrade mariadb-server-10.0.manpages:debian/tmp/usr/share/man/man1/mysql_upgrade.1 mariadb-server-10.0.postinst: # mysql_upgrade, called from the /etc/init.d/mysql start script, will mariadb-server-10.0.postinst: echo "[mysql_upgrade]" In mysql-5.6 packaging (which mariadb-10.0 is based on from about two years ago) the location seems to have been changed the location of the binary as you recommend but not the postinstall part: mysql-5.6/debian$ grep -R mysql_upgrade * additions/debian-start:MYUPGRADE="/usr/bin/mysql_upgrade --defaults-extra-file=/etc/mysql/debian.cnf" mysql-server-5.6.postinst: # admin might not already have run mysql_upgrade which adds them. mysql-server-5.6.postinst: # recreate the credentials file if not present or without mysql_upgrade stanza mysql-server-5.6.postinst: if [ -e "$dc" -a -n "`fgrep mysql_upgrade $dc 2>/dev/null`" ]; then mysql-server-5.6.postinst: echo "[mysql_upgrade]" >>$dc mysql-server-core-5.6.install:usr/bin/mysql_upgrade mysql-server-core-5.6.manpages:debian/tmp/usr/share/man/man1/mysql_upgrade.1 This is the contents of the mariadb-server-core-10.0 package: mariadb-10.0/debian$ cat mariadb-server-core-10.0.install usr/bin/innochecksum usr/sbin/mysqld usr/share/mysql/charsets usr/share/mysql/czech usr/share/mysql/danish usr/share/mysql/dutch usr/share/mysql/english usr/share/mysql/estonian usr/share/mysql/french usr/share/mysql/german usr/share/mysql/greek usr/share/mysql/hungarian usr/share/mysql/italian usr/share/mysql/japanese usr/share/mysql/korean usr/share/mysql/norwegian usr/share/mysql/norwegian-ny usr/share/mysql/polish usr/share/mysql/portuguese usr/share/mysql/romanian usr/share/mysql/russian usr/share/mysql/serbian usr/share/mysql/slovak usr/share/mysql/spanish usr/share/mysql/swedish usr/share/mysql/ukrainian ..and mysql-5.6: mysql-5.6/debian$ cat mysql-server-core-5.6.install usr/bin/innochecksum usr/bin/my_print_defaults usr/bin/mysql_install_db usr/bin/mysql_upgrade usr/sbin/mysqld usr/sbin/mysqld usr/share/mysql/bulgarian usr/share/mysql/charsets usr/share/mysql/charsets usr/share/mysql/czech usr/share/mysql/czech usr/share/mysql/danish usr/share/mysql/danish usr/share/mysql/dictionary.txt usr/share/mysql/dutch usr/share/mysql/dutch usr/share/mysql/english usr/share/mysql/english usr/share/mysql/estonian usr/share/mysql/estonian usr/share/mysql/fill_help_tables.sql usr/share/mysql/french usr/share/mysql/french usr/share/mysql/german usr/share/mysql/german usr/share/mysql/greek usr/share/mysql/greek usr/share/mysql/hungarian usr/share/mysql/hungarian usr/share/mysql/innodb_memcached_config.sql usr/share/mysql/italian usr/share/mysql/italian usr/share/mysql/japanese usr/share/mysql/japanese usr/share/mysql/korean usr/share/mysql/korean usr/share/mysql/my-default.cnf usr/share/mysql/mysql_security_commands.sql usr/share/mysql/mysql_system_tables.sql usr/share/mysql/mysql_system_tables_data.sql usr/share/mysql/norwegian usr/share/mysql/norwegian usr/share/mysql/norwegian-ny usr/share/mysql/norwegian-ny usr/share/mysql/polish usr/share/mysql/polish usr/share/mysql/portuguese usr/share/mysql/portuguese usr/share/mysql/romanian usr/share/mysql/romanian usr/share/mysql/russian usr/share/mysql/russian usr/share/mysql/serbian usr/share/mysql/serbian usr/share/mysql/slovak usr/share/mysql/slovak usr/share/mysql/spanish usr/share/mysql/spanish usr/share/mysql/swedish usr/share/mysql/swedish usr/share/mysql/ukrainian usr/share/mysql/ukrainian Solving this is _not_ straightforward (for me) because of two reasons: 1) I personally never used just the core package and I don't fully understand the motivation why it even exists. Is Akonadi the only use case? 2) The mysql-5.6 packaging is a bit messed up (double entries in install file, server-core having the mysql_upgrade binary but the postinst part and init file that could trigger it automatically are only in the server package) so I it would not make sense to model mariadb-10.0 packaging after it in this case. I will need to investigate this more at a later time.
