This playbook requires:

• ssh keys uploaded to the masternodes for ansible to log in
• ansible to be installed on the controlling machine (can be your local machine or another server)
• a hosts file on the controlling machine that specifies the IP addresses, ssh ports and login usernames of the masternodes
• an ansible vault file on the controlling machine with the encrypted passwords that are needed for sudo

Command I use to run this playbook with ansible:

$ ansible-playbook -i hosts --ask-vault-pass update_zcoin_mns.yml

Attention:

Version numbers are hardcoded and need to be checked and updated manually before running this playbook!

Lines 46 & 47 should read as
- /home/znode/.zcoin/zncache.dat
- /home/znode/.zcoin/znpayments.dat
Unless you really have the .zcoin folder in /home

Thanks, you're right! Fixed it.
