On Ubuntu 16.04 Xenial Xerus doesn't install. There's the following error:

The following packages have unmet dependencies:
ajenti : Depends: python-support (>= 0.90.0) but it is not installable
Depends: python-reconfigure (>= 0.1.46) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

After some try I've been able to install and made to work Ajenti on Ubuntu 16.04.

First downloaded and installed this:

sudo dpkg -i python-support_1.0.15_all.deb

Now ajenti installs without errors:

sudo apt-get install ajenti

Ajenti starts and you can login, but there's only an empty page, so next steps are needed.

Edit those files:

sudo vi /usr/lib/python2.7/dist-packages/socketio/
sudo vi /usr/lib/python2.7/dist-packages/socketio/

find this line in both files:

("Access-Control-Max-Age", 3600),

add double quotes:

("Access-Control-Max-Age", "3600"),

restart Ajenti:

sudo service ajenti restart

login again to the panel.
