BREAKING CHANGE: SQLite SourceGear Migration Compatibility
SQLite has migrated to SourceGear.sqlite3, which requires GLIBC 2.29+ and is incompatible with older end-of-life systems including Debian 10, Synology DSM, and Ubuntu 18.04. If you encounter SQLite-related errors, symlink libe_sqlite3.so to the application’s bin directory from your system’s native SQLite library instead. See the FAQ for details.
