This bug was fixed in the package coreutils - 8.32-3ubuntu1

---------------
coreutils (8.32-3ubuntu1) groovy; urgency=medium

  * Merge with Debian unstable (LP: #1888046). Remaining changes:
    - debian/rules:
      + Allow crossbuilding
      + Run tests
      + Ignore the cut-huge-range test failure on armhf, only seen on
        the buildds.
    - debian/tests:
      + Add dep8 tests
    - debian/patches/80_fedora_sysinfo.patch
      + Make 'uname -i -p' return the real processor/hardware,
        instead of unknown.
    - debian/patches/99_float_endian_detection.patch:
      + Fix detection of floating point endianness.
    - d/p/treat-devtmpfs-and-squashfs-as-dummy-filesystems.patch:
      + Avoid displaying snaps in output from df and other tools, by
        excluding display of squashfs filesystems.
        (LP #1219529, #1756595)
      + Exclude devtmpfs filesystems in output from df and other tools
        since it is a dummy filesystem.
        (LP #1219529)
  * Refresh d/patches/.
  * Fix FTBFS on ARM64.
    - d/p/restore-ls-behavior-8.31.patch: Upstream patch to restore
      coreutils ls' 8.31 behavior on removed directories, which is
      necessary to prevent using SYS_getdents that doesn't exist on
      ARM64.
    - d/p/improve-removed-directory-test.patch: Upstream patch to
      improve ls' removed-directory test.
