Recommended action: Pre-install extensions during image build (INSTALL x) or download the .duckdb_extension file and INSTALL from local path; set extension_directory/extension_directories to a writable/bundled path; for 404s check version/platform availability or INSTALL x FROM community/core_nightly. Option: Bundle extensions ahead of time [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. At image build: python -c "import duckdb; duckdb.sql('INSTALL httpfs')" (with network) 2. Or download the .duckdb_extension file and INSTALL '/path/httpfs.duckdb_extension' 3. Set extension_directory to a writable path if HOME is read-only Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
