+* What is =debuginfod=?
+- Relatively young (@@latex:$\sim$@@2019) project started by Red Hat.
+- It @@latex:\emph{@@"is a client/server [...] that automatically
+  distributes =ELF= / =DWARF= / source-code from servers to clients
+  such as debuggers across HTTP"@@latex:}@@.
+- The goal is to replace the need for =.ddeb= files (but it can do
+  more than that).
+
+* How does it work?
+- There's a =debuginfod= server (e.g., at
+  https://debuginfod.ubuntu.com) that indexes all available debuginfo
+  from several supported Ubuntu releases.
+#+BEAMER: \pause
+- Debugger-like tools (e.g., =GDB=) link against
+  =libdebuginfod=, which provides the client support.
+#+BEAMER: \pause
+- When the tool needs a certain debuginfo, it will contact the
+  =debuginfod= server (specified via the =DEBUGINFOD_URLS= shell
+  variable) and put a request for the debuginfo's =Build-ID=.
+#+BEAMER: \pause
+- If found, the server will then transmit the information over HTTP(S)
+  to the client.
+
+* How do I use it?
+:PROPERTIES:
+:BEAMER_OPT: fragile
+:END:
+- =GDB= on Jammy and Kinetic support using =debuginfod= to fetch debug
+  information.
+- From Kinetic onward, there is no need for manual intervention: the
+  system will automatically use Ubuntu's =debuginfod= service.
+- On Jammy, you can configure your system to use the service by doing:
+
+#+ATTR_LATEX: :options frame=single
+#+begin_src bash
+export DEBUGINFOD_URLS="https://debuginfod.ubuntu.com"
+#+end_src
+
+* Demo
+- Fasten your seat belts, please.
+
+* Future plans
+- Work on source code indexing (more demo!).
+- Index debug information from other producers (snaps, special PPAs).
+- Provide =debuginfod=-capable =GDBs= via =-backports= to previous
+  supported Ubuntu releases.
