Hi! I had the same issue and in my case I fixed with the following steps: (previous these steps I purged sendmail because I needed only postfix)
- searched all the remains of sendmail and removed from the places that I thought it would affect the boot process - on /etc/network/interfaces I deleted all the other lines added before - there remained only 2 lines (default ones) - purged the network-manager (but before I saved all the needed packages for a reinstall from an USB stick - .deb files) - added packages: plasma-nm, plasma-widget-networkmanagement, network-manager-gnome - checked all the remained errors from /var/log/upstart/ logs - in my case there were none left after reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1290217 Title: The overwriting error message was: Key file does not have group 'connectivity' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1290217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
