Looking around, the only source for this failure I could see is for when IPv6 is indeed disabled...
So I'll add some logic to the migration script not to migrate bridge settings if IPv6 is completely missing (as in /proc/sys/net/ipv6 doesn't exist) AND add logic to LXD to set disable_ipv6 to 0 for the bridge interface before attempting to set any IPv6 configuration. But while those two changes make sense, I'm not sure that they are actually relevant for you two since the output you gave me suggests that a new bridge interface should have had disable_ipv6 set to 0 (as a result of inheriting from the default)... Anyway, maybe we'll get lucky and my fix will actually sort this out because I couldn't find any other reason for a permission denied at ip addr add time other than that... -- 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
