This is still confusing and undocumented in Ubuntu 24.04.1 LTS I don't know why the extra /fsstnd subdirectory exists or why the MANDB_MAP for /usr/man and /usr/share/man should be different.
If you use "ln -s share/man /usr/man" then the easiest work-around is: # cd /var/cache/man # mv fsstnd/* . # rmdir fsstnd # ln -s . fsstnd Now "man -k" works fine. ** Also affects: man-db Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942063 Title: /usr/man symlink breaks apropos man -k due to fsstnd To manage notifications about this bug go to: https://bugs.launchpad.net/man-db/+bug/1942063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
