Today when I try to add new event on freshly-installed GNOME Calendar 3.20 (on Trisquel 8, based on Ubuntu Xenial) it gives no response so new event & calendar cannot be added. Later, I find the error message from console "Failed to execute program org.gnome.evolution.dataserver.Sources5" and I find the hint from Gerold Jens on Launchpad  it solves the issue correctly by installing "evolution-data-server" package.

Solution

$ sudo apt-get install evolution-data-server 

In my system, this will also install 4 dependency packages (800KB total): libedata-cal-1.2-28, libgeocode-glib0, libgweather-3-6, and libgweather-common.

Restart your GNOME Calendar and now you should be able to add new event and add new calendar. Thank you GNOME developers!

This article explains step by step how to upgrade GNOME Calendar to 3.22.1 in Ubuntu 16.10, 16.04, and 14.04 using GNOME3 Staging PPA. For your information, even in the latest stable Ubuntu 16.10 we have only the version 3.20 for GNOME Calendar. We can get the latest version by external repository, and that is what the PPA for. This article is written at 3 December 2016 with 3.22.1 version, so next time you may encounter this PPA version changed up to its maintainer.
