This seems to be similar to: https://github.com/juju/charm-tools/issues/625 Full details for recreating the issue are at the end of this description. Essentially in order to use git from charmcraft, pip needs to be pinned. Modern pip versions use git arguments that did not exist on older versions. Digging further in the charmcraft container I see: ``` root@charmcraft-cinder-lvm-8670388-0-0-amd64:~# /snap/charmcraft/x2/git/git-core/git --no-write-fetch-head unknown option: --no-write-fetch-head usage: git [--version] [--help] [-C <path>] [-c <name>=<value>] [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path] [-p | --paginate | -P | --no-pager] [--no-replace-objects] [--bare] [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>] <command> [<args>] ``` Full details: I'm hitting this on the following charm-cinder-lvm change. Note that it only occurs when the pin for pip<20.3 in charm-cinder-lvm/pip.sh is removed: https://review.opendev.org/c/openstack/charm-cinder-lvm/+/858566 ``` /tmp/charm-cinder-lvm$ tox -e build [21458/73924] build run-test-pre: PYTHONHASHSEED='0' build run-test: commands[0] | charmcraft clean Cleaned project 'cinder-lvm'. build run-test: commands[1] | charmcraft -v pack Starting charmcraft version 2.0.0 Logging execution to '/home/corey/snap/charmcraft/common/cache/charmcraft/log/charmcraft-20220923-161458.987807.log' Packing the charm.
