Actually, my issue is not specific to the RAMSES frontend, I just ran
"yt plot tests/DD0010/moving7_0010t"
which worked fine for me in 2.4, but fails in the current 3.0.

(yt-x86_64)[@lap186 ~/repos/yt-3.0]$  yt plot tests/DD0010/moving7_0010

So I attempted to bash install_script.sh the current 3.0 and that failed as
well:
