Public bug reported: The `perf` command-line tool expects a tips.txt file at /usr/share/doc/perf-tip/tips.txt, from which it displays random tips in `perf report` mode. If this file is not present (it is not on Ubuntu 22.04 LTS), `perf report` complains, both in interactive and in non- interactive mode, that:
> Cannot load tips.txt file, please install perf! Reproduction: $ mkdir tmpdir; cd tmpdir $ perf record ls $ perf report | cat The expected behaviour is that this message is not shown (and a (useful?) tip is shown instead). This has led to bug reports (and fixes) on various other Linux distributions: at least Fedora [1] and Arch [2].
