This seems as though volatility hasn't been installed correctly. As you can see here the source respository (and therefore what should be installed) includes a file in the volatility3.plugins.linux directory, so the volatility3.plugins module should have an attribute linux. Please try ensure a complete clone of the repository is present where you're running volatility, or install it using pip install volatility3.
