Fails to build with current Pythons: setuptools.extern.packaging.version.InvalidVersion: Invalid version: ''

The same problem is with libbtbb. This has been working fine earlier, but now fails:

As a temporary workaround, you can just set the version yourself to something. I set the version in host/build/python/specan_ui/setup.py to 1.0, it doesn't really matter what it is as long as it's not an empty string. You may have to do this on another file as well.

work fine as weel? i have the same problem
What type of versone you insert in file setup.py/core.py/dist.py

You can tell what files you need to add it to from the beginning of the Traceback:

[ 97%] Generating build/timestamp
Traceback (most recent call last):
File "/home/lisoant/hardware/ubertooth/host/build/python/specan_ui/setup.py", line 15, in setup(

This tells you that you have to add a version number to host/build/python/specan_ui/setup.py. When I did this, I put 0.8 but I don't believe there was any reason why I picked that version number specifically. This is what my file looks like:

from distutils.core import setup

setup(
    name        = "specan",
    description = "A tool for reading spectrum analyzer data from an Ubertooth device",
    author      = "Jared Boone, Michael Ossmann, Dominic Spill",
    url         = "https://github.com/greatscottgadgets/ubertooth/",
    license     = "GPL",
    version     = '0.8',
    package_dir = { '': '/home/braedon/aec/bluetooth/ubertooth-2020-12-R1/host/python/specan_ui' },
    packages    = ['specan'],
    classifiers=[
        'Development Status :: 5 - Beta',
        'Intended Audience :: Developers',
        'License :: OSI Approved :: GNU General Public License (GPL)',
        'Programming Language :: Python',
        'Operating System :: OS Independent',
    ],
)

After you do that and try to rebuild, you may get another error that's very similar but in a different file. Just do the same thing to find the other file and add a version into the setup.py file.
