Yeah I can’t remember how exactly but I was stuck for days and I googled a lot.
I have the same issue I hope you found a solution 
Hi Guys for everyone having troubles with pypykatz, I was trying as the lesson said, but when I used pypykats i got the parsing error we all are having, I uninstalled and reinstalled pypykatz and same parsing error, what i noticed was that on the windows machine in the lesson you had Local Security Authority Process and unser it CNG Key Isolation Credential Manager and Security Account manager but in mine i just had CNG and Security, I went to services started Credential Manager, re did the dump move it to my machine used pypykatz and problem solved. Hope this helps anyone
these were really interesting tasks 
IMPORTANT! In the resources section you can find some lists. They should be more clear about this.
From Credential Hunting in Linux
" Sometimes, we will not have any initial credentials available, and as the last step, we will need to bruteforce the credentials to available services to get access. From other hosts on the network, our colleagues were able to identify the user “Kira”, who in most cases had SSH access to other systems with the password “LoveYou1”. We have already provided a prepared list of passwords in the “Resources” section for simplicity’s purpose."
