Trouble with 'make obal' -Build failed!

[gerasimenkoao]

Hello!
I do OBAL on Raspberry Zero W
Best result is on Raspios Buster-armhf (build from 2021-05-70)
Other versions do not even reach this point (make obal)

Error message is:
Build failed
Traceback (most recent call last):
File "/home/admin/ardupilot/modules/waf/waflib/Task.py", line 348, in process ret = self.run()
File "Tools/ardupilotwaf/mavgen.py" line 54, in run from pymavlink.generator import mavgen

from future import standard_library ModuleNotFoundError: No module named 'future'
make: *** [Makefile:31: obal] Error 1

Need help.
Thanks in advance, Andrii
