Error "Unable to activate the adapter (...). Return code: -8"
On Linux, elevated privileges are needed in order to send Ethernet packets. Run your program with sudo to resolve this issue.
Error "Unable to load shared library 'libpcap' or one of its dependencies. ..."
If you are on Ubuntu 18: Libpcap is "preinstalled", but SharpPcap won't find it. There are various ways how to resolve it. One of them is to create a copy of symlink /user/lib/x86_64-linux-gnu/libpcap.so.0.8 to symlink libpcap.so in the same directory.
