### Bug Description When packing a go application with the experimental go framework, rockcraft fails with a `FileNotFoundError`. The full log is here: https://pastebin.canonical.com/p/xr627JZ8HQ/. ### To Reproduce Found following the build a rock for a Go application tutorial but without multi-pass: https://documentation.ubuntu.com/rockcraft/en/1.8.0/tutorial/go.html ``` go mod init example sudo snap install rockcraft --classic rockcraft init --profile go-framework ROCKCRAFT_ENABLE_EXPERIMENTAL_EXTENSIONS=True rockcraft pack ``` ### Environment OS: ubuntu@24.04 Rockcraft: 1.8.0 (latest/stable) Not running in multipass. ### rockcraft.yaml ```yaml name: my-rock-name # see https://documentation.ubuntu.com/rockcraft/en/1.8.0/explanation/bases/ # for more information about bases and using 'bare' bases for chiselled rocks base: bare # as an alternative, a ubuntu base can be used build-base: ubuntu@24.04 # build-base is required when the base is bare version: '0.1' # just for humans.
