### Bug Description In my `charmcraft.yaml` file I updated the charm version via the `build-snaps` directive, and then a `charmcraft pack` but the changes were not reflected, ie no new charm version was installed. Only when I ran `charmcraft clean` and another `charmcraft pack` it worked as intended and used the new charm version from the `charmcraft.yaml` configuration. ### To Reproduce - create a simple `charmcraft.yaml` with e.g. `build-snaps: [charm/2.x/stable]` - run `charmcraft pack` (which creates a container) - update `charmcraft.yaml` to `build-snaps: [charm]` - run `charmcraft pack` - the new charm version is not used (I noticed that as I added an option which is only available with the new charm version). ### Environment - Ubuntu 20.04 - charmcraft -> version 2.3.0 - using lxd containers ### charmcraft.yaml ```shell see above ``` ### Relevant log output ```shell none ```
