Hi Stéphane - I know this is closed but I came across a similar failure after migrating from 16.04 to 16.10. As above the migration of /etc/default/lxd-bridge failed and left me with no networking in the lxd containers.
After a lot of hunting I found that the migration script did not correctly handle the migration of the LXD_CONFILE setting. (I have some dnsmasq dhcp-host entries to ensure my containers get reliable IP4 addresses.) What I had in /etc/default/lxd-bridge was this... LXD_CONFILE="/etc/lxd/dnsmasq.conf" But what got set up by the migration script in: lxc network edit lxdbr0 raw.dnsmasq: conf-file /etc/lxd/pjr-dnsmasq.conf Note: this is missing an equals sign after conf-file and should be... raw.dnsmasq: conf-file=/etc/lxd/pjr-dnsmasq.conf Without that dnsmasq always fails and my hosts had no IP4 networking. Would be great if the migration script can be changed so that anyone else moving from 16.04 LTS doesn't have this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629540 Title: package lxd (not installed) 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/lxd/+bug/1629540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
