networkx has some breaking API changes between 1.x and 2.x which are non-trivial to resolve. To unbreak the use of cergen on buster the build has been adapted to use a forward-ported 1.11 package on a separate component for buster-wikimedia (component/cergen, which now also includes cergen itself).

CERGEN=yes DIST=buster-wikimedia pdebuild is needed to build the package in case anybody needs it :)

Huh, can you add that to the debian/README?

Yep yep already planning to, will do it tomorrow!

On puppetmaster2001 I cannot see /etc/apt/sources.list.d/buster-cergen.list, hence the new package version seems not available.. expected?

Yes, it's only installed on the active Puppet CA, i.e. currently puppetmaster1001.eqiad.wmnet
