Mate Desktop in a Singularity container?

The only other errors output are these:

I even trimmed down my definition such that I’m only installing epel-release, dbus-python, and gnome-keyring, which produces the same errors. I’ll look into those other possibilities and see if I turn something up.

Thanks.
