Hi Nicholas,

NVidia BPO is installable if libegl1-mesa is installed.

But anyway I think there are provides clauses missing in NVidia BPO, i.e.
libgl1-glvnd-nvidia-glx should Provide (and not only replace) libgl1
libegl1-glvnd-nvidia should Provide (and not only replace) libegl1

Now maybe I'm wrong but this is what the documentation tends to suggest :
https://www.debian.org/doc/debian-policy/#document-ch-relationships

Rgds,
