Main Windows Download link (Pro version) can be found here:

http://keepass.info/download.html

It can be installed under linux using

apt-get install keepass2 ca-certificates 

Keepass compiles plugins and requires the complete mono environment in order to do this.

apt-get install mono-complete ca-certificates 

Once plugins are copied into the /usr/lib/keepass2 directory, ensure to chmod 666 the plugin file.

for the googlesync plugin, the following is required:

download sync plugin, then extract the zip from http://sourceforge.net/projects/kp-googlesync/?source=typ_redirect

sudo cp GoogleSyncPlugin.plgx /usr/lib/keepass2
sudo apt-get install liblog4net1.2-cil
sudo cp /usr/lib/cli/log4net-1.2/log4net.dll /usr/lib/keepass2
sudo cp /usr/lib/mono/2.0/System.ServiceModel.Web.dll /usr/lib/keepass2
possibly also required is the import of the mozilla root certificates:
mozroots --import --sync

apt install golang

vi ~/.bashrc
export GOPATH=$HOME/gopath
export PATH=$GOPATH:$GOPATH/bin:$PATH

source ~/.bashrc

go get -u github.com/odeke-em/drive/cmd/drive

mkdir ~/gdrive
drive init ~/gdrive
open url, log into google, authorise drive, copy and paste authorization code.


cd ~/gdrive
drive pull Wulf.kdbx

vi ~/KeePass/keepass_trigger_load.sh

#!/bin/bash
cd ~/gdrive
drive pull -ignore-conflict -quiet Wulf.kdbx

vi ~/keepass_trigger_save.sh:

#!/bin/bash
cp ~/KeePass/Wulf.kdbx ~/gdrive
cd ~/gdrive
