Ubuntu 14.04 Server Not Rebooting (ifupdown network issue) It appears that with the latest bundle of Ubuntu updates, ifupdown breaks the server boot quite fantastically.
Resolution 1: Change the order that the updates are applied in [1] BACKUP SERVER! [2] apt-get update [3] apt-mark hold ifupdown [4] apt-get upgrade -y [5] apt-mark unhold ifupdown [6] apt-get upgrade -y [7] Check that the server reboots correctly Resolution 2: edit your network interfaces file, specifically looking for incorrect commands: example: post-up ip6tables-restore < /etc/iptables.up.rules This is clearly not correct since it is attempting to load IPV4 tables to IPV6 routes and will result in a network failure, thus preventing booting of the server. [1] nano /etc/network/interfaces [2] Remove incorrect post boot commands, ie. post-up ip6tables-restore < /etc/iptables.up.rules [3] apt-mark unhold ifupdown (If you previously had the package on hold) [4] apt-get upgrade -y [5] Check that the server reboots correctly. I am not sure where this bug came from @ubuntu but it is nasty, nasty, nasty! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301015 Title: Networking does not restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1301015/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
