Thank you for taking the time to report this bug and helping to make Ubuntu better.
This might be an issue between resolvconf and bind9 and when they get configured OR it might be that something else in overwriting what resolvconf is trying todo. Please could you try the following: cd /etc sudo ln -sf /etc/resolvconf/run/resolv.conf Please then try to update your system again. Please update this bug report if this does not resolve your issue or mark as 'Invalid' if it does. Marking importance as 'Low' for the time being pending response. ** Changed in: bind9 (Ubuntu) Status: New => Incomplete ** Changed in: bind9 (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bind9 in Ubuntu. https://bugs.launchpad.net/bugs/835825 Title: package bind9 1:9.7.3.dfsg-1ubuntu2.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/835825/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
