You have to perform following steps:

Check whether the error is false positive (script failed to extract
variables) or true positive (variable list changed).

If it is false positive:
- Fix this script.
- The same fix is needed in shadow package in shadow-login_defs-check.sh.

If it is true positive:
- Check-out shadow package and call shadow-login_defs-check.sh.
- Compare its output shadow-login_defs-check-util-linux.lst with
  util-linux-login_defs-vars.lst in the util-linux build directory.
- Update shadow shadow-login_defs-util-linux.patch, if needed.
- If shadow-login_defs-util-linux.patch was updated, update
  login_defs-support-for-util-linux symbol version in both shadow and
  util-linux spec files accordingly.
- Update checksum in this script.
- Possibly update su.default with these new list of su/runuser specific
  variables:

			sed -n 's/^.*logindefs_setenv*("[A-Z0-9_]*", "$[A-Z0-9_]*$".*$/\1/p'
	) | LC_ALL=C sort -u | tr '\n' ' ' | sed 's/ /, /g;s/, $//' >&2
	echo -e '\n' >&2

exit 1
else
	echo "OK" >&2
