> There's two separate issues: we don't package lockfile, because it's not a dependency of cachecontrol (it's only an optional depencency: https://github.com/ionrock/cachecontrol/blob/f93d8af93e6dcc98f6867d2a09d4f68f6acc135f/setup.py#L25). So lockfile needs to be added to pyproject.toml @pulsar17.

Currently there is no need to add `python3-lockfile`, because the package is only optional and even then deprecated.  means that inkscape 1.2 is now intentionally not fully supported for extensions manager.

But that's okay, because adding extensions can still be done manually by adding to `~/.config/inkscape/extensions/`
