我正在尝试在Ubuntu 20.04桌面上安装Snort 3.0。我使用手册作为这次安装的指南。一切都很顺利，安装似乎很顺利，但是，在第6页，用默认配置文件测试Snort，它希望我传递snort -c /usr/local/etc/snort/snort.lua，但我得到错误Error: Could not find requested DAQ moduel: pcap我昨天花了几个小时在谷歌上搜索，但找不到任何东西。现在，我是一个完全的初学者，当谈到Ubuntu。我需要安装什么存储库才能使其运行？谢谢！
更新所以我从tcpdump安装了pcap，但这并没有解决它。我仍然得到同样的错误。

http://www.tcpdump.org/release/libpcap-1.10.0.tar.gz

我通过了：

wget http://www.tcpdump.org/release/libpcap-1.10.0.tar.gz
tar -xzvf libpcap-1.10.0.tar.gz

安装很顺利。
然后我通过了：

/usr/local/bin/snort -V

请指示。谢谢你。
更新
看起来我已经有了最新的pcap版本。
