looking at openssh source code:
#define _PATH_DH_MODULI SSHDIR "/moduli"
/* Backwards compatibility */
#define _PATH_DH_PRIMES SSHDIR "/primes"

both paths are defined, with primes being a legacy/compat one.
Ubuntu only uses the current default /moduli path.

These are documented in ssh-keygen, you can see this manpage over here too http://manpages.ubuntu.com/manpages/xenial/en/man1/ssh-keygen.1.html#contenttoc3

Note, openssh supports and can be forced to use more combinations on client <-> server than available in the moduli, hence the caveat as per manpage. If one needs moduli beyond what's available in /moduli path, one may need to generate extra ones.

Nonetheless, please provide information as to how to reproduce this error ssh client in use, ssh server in use, and version details of both client and server. Ideally including architecture and exact package version numbers. The combined metadata on this bug report is inconsistent, and I'm failing to reproduce the described errors.
