Boot hangs and waits for network configuration for over a minute after upgrade from 13.10 to 14.04

[Kevin]

I just upgraded from lubuntu 13.04 to 14.10. After upgrading the boot process hangs and says that it is waiting for the network config. After some time it says that it will wait 60 seconds more and does so.

Don't know what's wrong here and fixed it by commenting out the relevant parts in /etc/init/failsafe.conf. So it works for me (though I don't think that is the preferred solution). Nevertheless I just want to report that there may be an issure.

Status changed to 'Confirmed' because the bug affects multiple users.

I also have this problem, but after about 2 minutes, boot is completed and after I log in, I have to start network-manager service because it is closed, otherwise I won't be able to use network and if I don't start it no network tray appears.

I upgraded from Ubuntu 14.04.1 LTS to 14.10 yesterday and immediately after the upgrade finished I rebooted and this problem appeared.

This solution worked for me: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1385709/comments/6 ;removing left-overs from a sendmail installation, maybe that was part of 14.04.
