#TIL that you can turn off the newfangled annoying "download stuff from debuginfod.ubuntu.com?" prompt every time #gdb runs, by unsetting DEBUGINFOD_URLS in the environment. That must have been annoying me ever since Ubuntu 24.04 came out, and I just sighed and said no to the prompt every time. But this evening a program of mine hung mysteriously on shutdown, and on investigation that turned out to be because Leak Sanitiser had invoked llvm-symbolizer to print backtraces, which defaults to trying to talk to the Ubuntu debuginfod servers, which currently seems to be ill and not answering questions. And llvm-symbolizer's man page mentioned that environment variable, which seems to be what triggers gdb to offer the same feature. If I'd known that two years ago I could have avoided two years of that annoying gdb prompt!

Oh, das ging schnell. Erstaunlicherweise ist diese schnelle Feststellung meines GdB keine Ablehnung, aber sie haben mir nur 40 und (daher) nicht das Merkzeichen G gegeben. Da sollte ich wohl Widerspruch einlegen. Hab ja sonst keine Probleme. 🙄 #GdB
