File "/usr/bin/compose-changelog", line 8, in import productmd.compose ImportError: No module named compose
productmd in fedora at least does not have compose
This module has been added to productmd only recently, so this is not in current rawhide package. I have bundled it here as a temporary measure.
I will close this as newer productmd has been packaged. Also I have removed the bundled module.
This issue has been migrated to Fedora Forge: https://forge.fedoraproject.org/pungi/compose-utils/issues/1
Please continue any further discussion there.
