Package: arp-scan Version: 1.10.0-1 Severity: normal Reading the NEWS.md file, it seems that arp-scan should be built with POSIX.1e capabilities support on Linux. Probably you want to add libcap-dev to Build-Depends (on Linux architectures) and try "setcap cap_net_raw+p /usr/sbin/arp-scan" in the postinst so that arp-scan can be run by an ordinary user.
