Debuginfod in Ubuntu
summary
Ubuntu runs a debuginfod server that downloads debug info by build ID over HTTPS using libdebuginfod and GDB, indexing bionic/focal/jammy/kinetic/lunar and federating with Debian; the service pulls transitive library symbols into ~/.cache/debuginfod (no automatic cleanup), supports cross-arch targets, and the demo shows a modified server that does source code indexing over the wire so GDB finds sources without apt-get source. Backend uses ddab archives, BSD tar for extraction and a ~150 GB SQLite index; snaps and PPAs are next.
