### Bug Description With a new charm created with `charmcraft init` will minimum code added, and not added dependencies, the first `charmcraft pack` took 30+ mins. From the logs, most of the execution was fine until `Emitter: Pausing control of the terminal`, which was stuck for almost 30 mins. ### To Reproduce I have only encountered this issue once. 1. `charmcraft init` to create a new charm 2. `charmcraft pack` ### Environment Ubuntu 22.04 charmcraft 3.5.2 lxd 5.21.3 LTS ### charmcraft.yaml ```yaml # This file configures Charmcraft. # See https://canonical-charmcraft.readthedocs-hosted.com/en/stable/reference/files/charmcraft-yaml-file/ type: charm name: upgrade-on-error title: Charm Template summary: A very short one-line summary of the charm. description: | A single sentence that says what the charm is, concisely and memorably.
