FWIW, the static, predictable URL for the PyPI package is

@alfredo.ardito re-installing caffeine and these python packages worked for me: python-docopt, python-ewmh, python-setproctitle, python-wheel, python-xlib

I believe its something about last python update

It always used to work. I had this lately

@alfredo.ardito That's odd. Was this a one-time thing, or is it consistent?

Caffeine not executing anymore.
I uninstalled and reinstalled it again without errors. When I run it it halts displaying the following error:

@Demeter That behaviour is triggered if you have app indicators in your system (rather than a classic systray).

It's only active if libappindicator-gtk3 is installed.

Is it possible to switch caffeine just with left click on icon? Now works just popup menu via right click, then Enable - Disable... (MATE)

Yup, will update the pkgrel in a bit.
