### Check existing issues - [x] I've verified that this bug isn't described by any existing issues. ### Bug description When a part like the following ``` parts: fastapi-framework/dependencies: plugin: nil stage-packages: - python3-venv ``` is added to a `rockcraft.yaml` file with at least base `ubuntu@24.04`, it creates a `/etc/ssl/certs/ca-certificates.crt` that is copied from the building machine. This is incorrect, as the scripts for the `ca-certificates` package should not run, and so that file should not be in the final rock because of that part. That is currently breaking several 12-factor extensions when not using base bare. ### Steps to reproduce Follow the tutorial in https://documentation.ubuntu.com/rockcraft/latest/tutorial/fastapi/ and update the base to ubuntu@24.04. ### Environment Reproducible when building with lxd with rockcraft as of today, for example v1.19.0 with revision 4543. ### rockcraft.yaml ```yaml If the issue is specific to a project, share its `rockcraft.yaml`. This field automatically renders as YAML, so you don't need to add special formatting. ``` ### Log output ```shell Provide any relevant logging. This field automatically renders as a log, so you don't need to add special formatting. ```
