Package: mariadb-server-10.3 Version: 1:10.3.17-0+deb10u1 After removing a bunch of "unnecessary" libraries yesterday I discovered that mariadb would not restart. After many seconds of failure, the only worthwhile log entry is a vague message that suggests it would like to have libjemalloc.so.1, but doesn't really need it.
Turns out mysqld will not start without it installed. But libjemalloc1 doesn't exist in stable. I downloaded and installed libjemalloc1_3.6.0-3_amd64.deb from Jessie and mysql started right up. So mariadb-server-10.3 needs to depend on libjemalloc1 which needs to be put back in stable. Or have it compiled for and depend on libjemalloc2, which is in stable. # /etc/init.d/mysql start [....] Starting MariaDB database server: mysqld . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . failed!
