Hi,
i’m using mint 18.2 too and i never had this problem.
Just follow these instructions step by step

Installing Kee with KeePassRPC for KeePass Password Safe (instructions)

These instructions explain how to configure Kee to use KeePass as the storage location for protected passwords. If you use Kee Vault it is not necessary to follow these instructions, although advanced users may still wish to - read about using Kee with Kee Vault and KeePass first though. Quick instructions Install KeePass dependencies (Windows users can skip this step; Linux and Mac users need to install the latest version of Mono - usually called “mono-complete”) Install KeePass Password Safe…

# add ppa repo to access latest version of KeePass
sudo add-apt-repository ppa:jtaylor/keepass

# update local repo details to ensure the latest KeePass is selected later
sudo apt-get update

# Install Mono
sudo apt-get install mono-complete

# Install KeePass
sudo apt-get install keepass2

# Create plugins folder
sudo mkdir /usr/lib/keepass2/plugins

# Install curl and jq (required only for ease of installing the latest version of KeePassRPC)
sudo apt install curl
sudo apt install jq

# Put the latest version of KeePassRPC into the plugins folder created earlier
curl -s https://api.github.com/repos/kee-org/keepassrpc/releases/latest | jq -r ".assets[] | select(.name | test(\"KeePassRPC.plgx\")) | .browser_download_url" | xargs sudo curl -s -L -o "/usr/lib/keepass2/plugins/KeePassRPC.plgx"
