Summary

• Re-enable macos-smoke-test on macos-14 / macos-14-large without Homebrew libgit2@1.7, using the pygit2 wheel's vendored libgit2.
• Stop installing Homebrew libgit2 in install-macos-build-deps.
• Run uv lock after charmcraft init so the machine-profile (uv plugin) pack can succeed.

Fixes #2605

Test plan

• Local: make setup on Apple Silicon (no Homebrew libgit2)
• Local: pygit2 imports with vendored .dylibs
• Local: Multipass init + uv lock + pack → *.charm
• Local: pre-commit / prettier on changed files
• Local: make test-fast (3 pre-existing platforms-multi-base failures on Apple Silicon; unrelated)
• CI: macos-smoke-test passes on macos-14 and macos-14-large

• I've followed the contribution guidelines.
• I've signed the CLA.
• I've successfully run make lint && make test. (N/A — CI/Makefile smoke re-enable; verified with local Multipass pack, pre-commit, and make test-fast)
• I've added or updated any relevant documentation.
• In documents I changed, I added a meta description if one was missing.
• I've updated the relevant release notes.

We actually have to do significantly more for multipass now. We debugged this at canonical/multipass#4588

The short version is to copy these bits: https://github.com/lengau/setup-multipass/blob/d7ac69cac08d7d82da2518868b1ffe742a607e33/action.yaml#L35-L46

[Omjaiswal26]

Thanks — applied the setup-multipass workaround from the linked action (wait on multipass list, find --force-update, passphrase + sudo wrapper for canonical/multipass#4588). Also pinned the smoke-job Actions to SHAs for zizmor. Ready for another look / CI once workflows are approved.

PermissionError: [Errno 13] Permission denied: '/root/project/charmcraft.yaml'

Interesting... I would guess this is some side-effect of the permissions stuff we did with multipass?

[Omjaiswal26]

Agreed that this looks like a side-effect of the sudo multipass wrapper: mounts run as root while the project is owned by the runner user.

Would chmod -R a+rX . before pack be an acceptable smoke-test workaround, or do you prefer something else (e.g. UID maps in craft-providers)?

[lengau]

Yeah I think the permissions stuff is fine. We're already deviating from what a macos desktop would look like. Thanks!

Suggested change

	# libgit2 is provided by the pygit2 macOS wheel; do not brew install libgit2@1.7
	# (deprecated/unavailable). See https://github.com/canonical/charmcraft/issues/2605
	endif
	endif

[lengau]

@Omjaiswal26 it looks like there's still a permissions issue with the macos smoke test :-/

[lengau]

This is still failing :/

[Omjaiswal26]

yeah, chmod didn't fix it. ci still fails opening /root/project/charmcraft.yaml inside the vm.

i've found two possible ways to keep pack:

1. pass a uid/gid map. multipass.py already supports --uid-map / --gid-map, but the project mount never passes them. we'd map the runner user to 0 so the files look like root's in the vm. that change is in craft-providers and craft-application.

2. copy the project into the vm, pack there, and copy the .charm back. workaround only in this workflow.

i'd rather do (1). what do you think?
