### Issues Discovered & Fixes Needed:
|
||||
- [ ] **Binary Path Issue**: The workflow assumes `osbuild` is a standalone binary, but it's actually a Python package
|
||||
- **Current**: `cp osbuild debian/debian-forge/usr/bin/debian-forge`
|
||||
- **Fix**: Use Python entry point: `osbuild = osbuild.main_cli:osbuild_cli`
|
||||
- **Solution**: The `debian-forge` package should install the Python entry point, not copy a binary
|
||||
- **Update**: Modify debian/rules to use `dh_python3` properly for console scripts
|
||||
|
||||
### Next Actions:
|
||||
1. **Fix debian/rules** - Update to handle Python entry points correctly
|
||||
2. **Test local build** - Verify packages can be built locally
|
||||
3. **Trigger CI** - Push fixes and let Forgejo CI run the workflow
|
||||
4. **Verify packages** - Test that all 8 packages install and work correctly
