Package: libnumbertext-tools Version: 1.0-2 Severity: normal $ dpkg -L libnumbertext-tools [...] /usr/lib/libnumbertext/spellout
The tool is meant to be invoked by the end user, but is not located in a directory in $PATH. I would expect it to go in /usr/bin (and have a corresponding man page in /usr/share/man/man1). Also: $ /usr/lib/libnumbertext/spellout -l en 101 spellout: missing language module Using "strace", we see: $ strace -e file /usr/lib/libnumbertext/spellout -l en 101 [...] openat(AT_FDCWD, "en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/usr/share/numbertext/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/usr/share/numbertext/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "data/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "data/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "data/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "data/en.sor", O_RDONLY) = -1 ENOENT (No such file or directory) It looks first in "en.sor" in the current directory, which is a security vulnerability (for instance when run in /tmp where some attacker could have planted a malicious "en.sor" file). And then in "/usr/share/numbertext" while "libnumbertext-data" installs those files in "/usr/share/libnumbertext" instead. A work around is to run: $ /usr/lib/libnumbertext/spellout -l /usr/share/libnumbertext/en 101 one hundred one Though it doesn't work for en-GB for which you'd need: $ (cd /usr/share/libnumbertext && /usr/lib/libnumbertext/spellout -l en-GB 101) one hundred and one (but again looking in the current directory is a bad idea, so I'd expect that one to stop working in a future version). $ /usr/lib/libnumbertext/spellout -l /usr/share/libnumbertext/en-GB 101 one hundred one -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-updates'), (500, 'oldstable-updates'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.17.0-3-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libnumbertext-tools depends on: ii libc6 2.27-5 ii libgcc1 1:8.2.0-4 ii libnumbertext-1.0-0 1.0-2 ii libstdc++6 8.2.0-4 libnumbertext-tools recommends no packages. libnumbertext-tools suggests no packages. -- debconf-show failed
