Ajay,
Just rebuilt my Raspberry Pi with ubuntu 20.10 and re-do the installation
again. I still get the python2-cffi error, since the installation process
expecting the package python3-cffi-backend on the Pi to be at least version
1.14.4-0, and the command running the command 'apt install
python3-cffi-backend' doesn't really help within the distribution, since it
keeps downloading the same version (1.14.2-1 in ubuntu 20.10). I have to
change the /etc/apt/sources.list to add the hirsute repository which
include python3-cffi-backend version 1.14.4-1 that satisfies the condition
for installation of openwisp2. That went well, but now I have a new error
at the "migrage" step, which indicating that it doesn't find the module
'celery', just wondering if you can help troubleshoot that!? Error message
below.
Thanks for your help
