Should this package move away from python2 now that it's EOLd?

Hi. I now have an error when trying to run scapy from the cli or when doing a "from scapy.all import *"

Traceback (most recent call last):
  File "/usr/lib/python3.7/site-packages/pkg_resources/__init__.py", line 583, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3.7/site-packages/pkg_resources/__init__.py", line 900, in require
    needed = self.resolve(parse_requirements(requirements))

pkg_resources.VersionConflict: (scapy git-archive.devbad14cb1a (/usr/lib/python3.7/site-packages), Requirement.parse('scapy==2.4.3rc1.dev105'))

During handling of the above exception, another exception occurred:

Totally @Cyber_STX. You need to apply the following patch to PKGBUILD:

diff --git a/PKGBUILD b/PKGBUILD

Hi there,

There is an error when trying to install this package:

==> Starting prepare()...
sed: can't read bin/*: No such file or directory
==> ERROR: A failure occurred in prepare().
    Aborting...
Error making: scapy-git

Cheers

gonna try it a bit and create a split package out of it so the libs support both. will take a bit of rewrite and testing but it will happen.

Hi @plt

Sure, I think it would be a good idea to switch to python 3, I spoke with one of the dev and the port is going well. Reported a bug and it was fixed in 2 hours. I'm using a custom script right now to update it from the git but clearly would prefer if this package was made to be compatible with both.

Hi,

@Cyber_STX that should be fixed now.

We should probably switch to Python 3 BTW, since 2.4 (including RC) are compatible with both versions, and have a python2-scapy including only the Python library. What do you think?

Hi, since the last version 2.4-rc1, we cannot install this package anymore. Here is the log report:

==> ERROR: pkgver is not allowed to contain colons, hyphens or whitespace. ==> ERROR: pkgver() generated an invalid version: 2.4-rc1 :: Unable to build scapy-git - makepkg exited with code: 1

Thanks
