Cannot package Python3 package - missing binary
Metadata
Current evaluation
Snapcraft 2.43.1 build fails with FileNotFoundError for bin/mariner in prime during _wrap_exe; app command points to a binary the Python package does not install. 7.6 years old, no maintainer interaction, snapcraft 2.x EOL and code path removed.
Suggested action: close stale
Reason: The issue targets snapcraft 2.43.1 (Ubuntu 18.04 era), and the failing code path snapcraft/internal/meta/_snap_packaging.py no longer exists in the current codebase (repo layout shows snapcraft/meta/ without the internal/ prefix). Related issue #1884683 explicitly notes the 2.x code path is gone. The root cause is a user configuration problem — the app command points to bin/mariner which the poetry-setup build does not install to prime/bin — making this a support question on an EOL version.

We would appreciate it if you created a bug report at
https://launchpad.net/snapcraft/+filebug with the above text included.
You can find the snapcraft.yaml here https://gitlab.com/radek-sprta/mariner/blob/90a6fb89c4354223ab844d5e14d77ec9f5d75db7/snapcraft.yaml. For the above test, I have used setup.py generated by poetry-setup (https://pypi.org/project/poetry-setup/). python3 setup.py bdist_wheel produces a valid package.
