However, when I used that solution, I do not get the warning but the problem continues.但是,当我使用该解决方案时,我没有收到警告,但问题仍然存在。

PS In Ubuntu, when I use ifconfig I get the following: PS 在 Ubuntu 中,当我使用ifconfig时,我得到以下信息:
PS #2 I uninstalled Ubuntu 20.04 and installed Ubuntu 18.04 and I still get the same problem. PS #2 我卸载了 Ubuntu 20.04 并安装了 Ubuntu 18.04,但我仍然遇到同样的问题。
PS #3 I installed Ubuntu 20.04 in an Oracle Virtual Box Machine, and I got a different message that got me some ideas about the possible causes of the problem. PS #3 我在 Oracle Virtual Box Machine 中安装了 Ubuntu 20.04,我收到了一条不同的消息,让我对问题的可能原因有了一些想法。 I posted a solution.
我发布了一个解决方案。 Please read it, and let me know what you think.
请阅读它,让我知道你的想法。
It seems that the cause of the error is that as I am not using a wired connection, I am not using the network card.似乎错误的原因是因为我没有使用有线连接,所以我没有使用网卡。 For that reason, the
Ether()
function cannot be used.因此,无法使用
Ether()
函数。 As every network card has a unique Mac address, the Mac address cannot be used.由于每个网卡都有唯一的 Mac 地址,因此无法使用 Mac 地址。 That, in my opinion, is the cause of the error.
在我看来,这是错误的原因。 Of course, I would love to have an opinion of somebody who knows more about the subject.
当然,我很想听听对这个主题有更多了解的人的意见。 My college degree is in mathematics.
我的大学学位是数学。 In my last attempt, I installed Scapy on an Oracle Virtual Box Machine, and I am getting the following message:
在我最后一次尝试中,我在 Oracle Virtual Box 机器上安装了Scapy ,我收到以下消息:
WARNING: getmacbyip failed on [Errno 1] Operation not permitted WARNING: Mac address to reach destination not found. WARNING: getmacbyip failed on [Errno 1] Operation not allowed WARNING: Mac address to reach destination not found. Using broadcast.
使用广播。
What do you think?你怎么看?
@Carcigenicate advised me to use the route command in Linux. @Carcigenicate 建议我在 Linux 中使用 route 命令。
Here is the info that I get when I use the command route in the Ubuntu terminal that is in my Oracle virtual box machine.这是我在 Oracle 虚拟机中的 Ubuntu 终端中使用命令路由时获得的信息。
When I use the command route in the Ubuntu terminal that is in my Windows 10 Pro Laptop, I get the following:当我在 Windows 10 Pro 笔记本电脑中的 Ubuntu 终端中使用命令路由时,我得到以下信息:
At this time, following the tip of @Carcigenicate, we find that the Gateway is 0.0.0.0这个时候,按照@Carcigenicate的提示,我们发现Gateway是0.0.0.0
What that exactly means?这究竟意味着什么? Not sure.
没有把握。 Check this link: https://en.wikipedia.org/wiki/0.0.0.0

I forgot to mention that my machine is a corporate machine.我忘了提到我的机器是公司机器。 So, most likely my machine has some IT security software that causes that behavior.
所以,我的机器很可能有一些导致这种行为的 IT 安全软件。
I too faced the same problem:我也面临同样的问题:
