Edit this:
I found a workaround:
Edit the malfind.py file at /usr/lib/python2.7/dist-packages/volatility/plugins/malware/malfind.py

change the short option at Line 189, Original is Capital C letter. In my case I change it to small c letter
config.add_option("CASE", short_option = 'c', default = False, action = 'store_true',

change the short option at Line 195. Original is Capital Y Letter. In my case I change it to capital U letter
config.add_option('YARA-RULES', short_option = 'U', default = None,

Make sure to backup the original file.

This issue is still in the latest SIFT FYI ...

Looks like this is the case of conflicting plugins unfortunately. You can try disabling the malware one for now. We try to be very selective in which plugins are added and sometimes conflicts arise because authors use the same CLI options.
