Maybe that there is a syntax error; you might need a semicolon before the N (at least in some versions of sed). Or that it doesn't delete the preceding line as well as the next line; but that was included in the description of what it does.
anhtt: if you have a problem, please describe it so that it can be solved. "Does not work" is not sufficient information. If there is an error message, include it here. If the command does not do what you expect, describe what it does, and what you expected.
Is the requirement to do this in sed negotiable? It's fairly trivial with awk or perl, and rather tricky to do in sed.

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
