[Bug 2127851] Re: rust-coreutils stats handling breaks wireguard's wg-quick

Wed Feb 11 00:17:14 UTC 2026

This bug was fixed in the package rust-coreutils - 0.6.0-0ubuntu1

---------------
rust-coreutils (0.6.0-0ubuntu1) resolute; urgency=medium

  * New usptream version (LP: #2139697)
  * Fixes:
    - comm does not work as expected with process substitution (LP: #2138315)
    - git: FTBFS in Resolute (LP: #2138217)
    - tee with multiple --append fails in rust corutils (LP: #2134578)
    - echo 1 | sort | head -n0: sort: write failed: 'standard output':
      Broken pipe (LP: #2133156)
    - env: Rust unwrap with UTF-8 symbols in environment variables
      (LP: #2132941)
    - "du" is double-counting hard links when multiple arguments specified
      (LP: #2132245)
    - dd: O_DIRECT partial block writes fail (LP: #2132150)
    - date does not support localized output (LP: #2130859)
    - SSH sessions blocked on unavailable automounts by default in Ubuntu 25.10
      (LP: #2130843)
    - rust-coreutils 'shred' refuses to write to a device (LP: #2130396)
    - rust-coreutils stats handling breaks wireguard's wg-quick (LP: #2127851)
    - rust-coreutils:dd: Broken pipe (LP: #2125943)
    - /usr/bin/sort: -k option does not behave as GNU's sort (LP: #2125504)
    - uutils wc crashed with SIGABRT on logout (LP: #2122166)
    - who, pinky are empty - need to talk to logind (LP: #2117771)
  * Drop applied patches:
    - use-mem-zeroed.diff: The timespec C-binding struct has been replaced
      by the safe abstraction nix::sys::time::TimeSpec. Padding should now
      be handled internally for 32-bit architectures.
  * Refresh patches:
    - Tweak-release-build-profile.patch
    - build-stty.patch
    - dd-ensure-full-writes.patch
    - fix-prefix.diff
    - glibc-2.42.patch
    - require-utilities-to-be-invoked-using-matching-path.patch
    - use-l10n-translations-in-makefile.patch
    - workspace-exclude.patch
  * Add patch:
    - prevent-stty-termios2-on-ppc64el.patch: The termios2 header is not
      always available or exposed on ppc64el systems. Use the standard termios
      interface instead to avoid build failures on such systems.
  * Skip failing tests:
    (s390x)
    - test_env::test_simulation_of_terminal_for_stdout_only
    - test_nohup::test_nohup_stderr_to_stdout
    - test_nohup::test_nohup_with_pseudo_terminal_emulation_on_stdin_stdout_stderr_get_replaced
    - test_touch::test_touch_changes_time_of_file_in_stdout
    (amd64v3)
    - test_dd::test_stdin_stdout_skip_w_multiplier
  * Re-enable previously failing tests:
    - test_chown::test_chown_only_group_id_nonexistent_group
    - test_chown::test_chown_only_user_id_nonexistent_user
    - test_expr::test_long_input
    - test_factor::test_parallel
    - test_install::test_install_and_strip
    - test_install::test_install_and_strip_with_program
    - test_ls::test_device_number
    - test_ls::test_localized_possible_values
    - test_od::test_od_options_after_filename
    - test_od::test_suppress_duplicates
    - test_sort::
