Hello.

I already found the solution to the problem, my scapy/ppp.py has not defined the variables PPPoED_Tags and PPPoED_Tag. Searching online I found that it's need the minimum version of scapy 2.4.2.

Rereading the manual I have seen it put (Ubuntu), so quoted without further clarification. I think maybe it would be advisable to clarify that it is essential to use Ubuntu - Xubuntu 20.04 LTS (at least), since it installs versions of Python 3.8.5 and Python3-scapy 2.4.3-4, with which Python programs work at first.

I installed Xubuntu 20.04 LTS on a Virtualbox machine. I proceeded to install Python and Scapy and then changed the configuration of the virtualbox network card to bridge mode, set the IP parameters in the virtual machine and the Python programs worked to the first one and so I could install Openwrt without problems.

Thanks.
