Similar to #14, this happened to me doing do-release-upgrade to 17.04 beta after purging gnome3-team ppas. I was able to get internet connection working via some manual hacks I came across, but NetworkManager not working properly meant that Evolution thought I was offline. Finally, after 5 days, discovered this bug and executing touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf seems to have fixed things.

With these same settings, after upgrading to ubuntu 16.10, eth0 appears as unmanaged in nm-applet. If I modify /etc/network/interfaces and add auto eth0 iface eth0 inet dhcp And set managed=true in NetworkManager.conf [ifupdown] section, eth0 is still unmanaged despite it does get an IP from DHCP server. This is happening in my five computers (two laptops and three desktops).
