I'm very stuck on this issue and been trying to find a solution.
I've installed Maya 2022 on Ubuntu following the instructions here. After a few issues with the licenser I got it to work. However, I have not been able to get Arnold to work.
When I start Maya I get no errors or warnings from the terminal, but when the main window shows I have a warning:
// Warning: file: /usr/autodesk/maya2022/scripts/others/supportRenderers.mel line 67: The renderer "arnold" used by this scene, is not currently available. The "mayaSoftware" renderer will be used instead. To prevent this message from being displayed in the future, set the environment variable: MAYA_NO_WARNING_FOR_MISSING_DEFAULT_RENDERER=1 //
I then go to Windows->Setting/Preferences->Plug in manager
I then find mtoa.so and click load, but then Maya has a Fatal Error. This then appears in the terminal:

while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
My first hunch was Python, but python appears to be installed correctly on the Laptop and my looking for reasons for this error have all come up with no real results (may be I'm googling the wrong terms).
Anyone able to figure out whats going on? I've tried re-installing Arnold several times and its made no change.
Solved! Go to Solution.
