I've been trying to follow the steps highlighted here: https://cloudinit.readthedocs.io/en/19.3/topics/hacking.html to push a branch of cloud-init to by launchpad account, in order to link it to my github account.

Basically running:
git clone https://git.launchpad.net/cloud-init
cd cloud-init
git remote add USER ssh://USER@git.launchpad.net/~USER/cloud-init
git push USER master

With the last command timing out with "remote error: Unexpected Zope exception". Both git 2.13 and git 2.17 produced the same outcome.
