Hi,
I have orphaned both python-sphinxcontrib-seqdiag and
python-sphinxcontrib-blockdiag. The packages depend on python-seqdiag and
python-blockdiag, respectively, which are already orphan, and they have
been failing to install for quite some time.
If there is any interest in keeping the package, feel free to do so, but
keep in mind their dependencies will need to be maintained, too.
Regards,
Javier
