I (as part of the pkg-giraffe team) intent to orphan src:kopanocore.
The pkg-giraffe-team is happy to offer help and guidance for interested people which want to work on kopanocore (and also on related packages) within Debian.
Can you move the git repository to the /debian space on salsa.d.o? That would help anyone picking up the package.I might do a QA upload applying the FTBFS patches sitting in the BTS, nothing more ;-)
Thanks. Andreas
