Package: release.debian.org Severity: normal User: release.debian.org@packages.debian.org Usertags: binnmu nmu ns3_3.22+dfsg-1 . ALL . unstable . -m "Rebuild for libstdc++ transition" It was found that there's package in the archive makes use of ns3 when the binary is present, but no dependency is declared[1]. To avoid such problem please binNMU ns3 on all architectures. Thanks, Aron [1]https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=791219#21
