Debian 9 distribution package failed on multiple-server non-root installation

Build tested: 1.1.0

Root installation: single-server, 1um2pm, both deb and binary packages
Nonroot installation: single-server, 1um2pm, binary packages
All tests passed except
binary package for non root 1um2pm installation. It worked for single-server, but not multi-servers.
postConfigure returned these errors:
cannot create /etc/rc.local: Permission denied
cannot create /etc/rc.local: Permission denied
NOTE: I saw errors on Centos 7 recently and I thought they have been fixed.
