The objective of this post is to install keepass2, keefox, keecloud on Kubuntu 16.04.

Install keepass2

sudo aptitude install keepass2

Install keefox

Just after the installation, keefox will provide a link to a local file (KeePassRPC.plgx) that needs to be copied into the « plugins » directory of the keepass2 installation.

Furthermore, you need to adjust the path to the Keepass installation (you can change this setting in Firefox > Options > Keefox > Keepass).

Install the plugins

Keepass2 installation directory is:

/usr/lib/keepass2

I downloaded all the plugins concerned (the files that finish in *.plgx) in a subdirectory

sudo mkdir /usr/lib/keepass2/plugins
sudo cp Téléchargements/KeePassRPC.plgx /usr/lib/keepass2/plugins/
sudo cp Téléchargements/KeeCloud-1.2.0.3.plgx /usr/lib/keepass2/plugins/

You also need to install mono-complete

sudo aptitude install mono-complete

Integrate with your desktop environment (KDE 5)

This come from the following resource: https://github.com/dlech/Keebuntu

sudo apt-add-repository ppa:dlech/keepass2-plugins
sudo apt-get update
sudo apt-get install keepass2-plugin-application-indicator

You can now start Keepass2. The plugins should be compiled, and the installation of Keefox should be complete.
