AttributeError Exception at push: 'DiskObjectStore' object has no attribute 'generate_pack_data'

Hello, trying for the first time hg-git this morning on a Bionic Beaver everything ran smoothly, but installing it now on a Xenial Xerus laptop and using it, that exception was raised. Reporting it just in case it is useful. Thanks.

Try updating dulwich
pip install dulwich --upgrade

Thanks for the idea, but I have the same problem after updating to very recent versions Mercurial 4.9.1, hggit 0.8.12, and dulwich 0.18.5 - on dulwich 0.19.11 there is another, different issue (module dulwich.errors not found) that I have reported on the dulwich page.

The same issue is being reported on the bitbucket project so I will watch it and see how this develops:
https://bitbucket.org/durin42/hg-git/issues/262/attributeerror-diskobjectstore-object-has

EDIT: The issue was solved by using dulwich 0.19.11 BUT installed via pip2 instead of via pip (!?). Leave this info here just in case anyone finds it useful.

I am trying to migrate my code from Mercurial to Git. I have Mercurial 3.9.2 installed in my system with hg-git from github (and i have pointed the hg-git repository in mercurial.ini file) with Python 2.7.15 and dulwich 0.19.11 . But i am getting the below error while doing so.

It would be of great help if we could get a feasible solution for the same.

Thanks in advance !!
