Looking at your log i see: Setting up ubuntu-session (3.24.1-0ubuntu8) ...
The script to handle the migration was added in ubuntu-session 3.24.1-0ubuntu11, which was published on 2017-07-06 (later than your upgrade log). Perhaps it had been held in artful-proposed for a couple days. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1703358 Title: Display manager defaults to lightdm on upgrade Status in gnome-session package in Ubuntu: New Bug description: When I upgraded Artful earlier today using "sudo apt upgrade", I was prompted to pick between gdm3 and lightdm. lightdm was selected by default. I suspect that if I'd been running non-interactively, lightdm would have been selected, which is incorrect for our transition to GNOME. This machine was originally installed using an early Artful daily. I've been upgrading it regularly. Previously I had the system break due to some Unity components getting unseeded and thus autoremoved, which I reverted by downgrading ubuntu-desktop (and the seeds were fixed). On some subsequent upgrade my desktop switched from Unity to GNOME smoothly (except needing synaptics removing manually, which is known). I do not recall which display manager I was seeing at the time (though I do recall that the lock screen became the more minimal GNOME one). Then, today, on upgrade, I got asked about the display manager switch.
