[xubuntu, budgie & mate] ISO boots directly to desktop

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:

Same issue happens when using qemu/kvm - however here I do actually see the Try/Install dialogue appear fleetingly - I assume that if I wasn't using SSD and booting directly from the iso rather than a usb - I would fleetingly see the dialogue there.

Checked the following iso's:

Budgie from 12/4 - looks to hang about at a login prompt, then boots to
desktop.
Mate from 13/4 - looks to hang about at a login prompt, then boots to
desktop.

Ubuntu from 9/4 - boots to Try/Install Dialogue

Lubuntu doesn't appear to use that dialogue - choice of try and install
at the first menu for that iso.

Status changed to 'Confirmed' because the bug affects multiple users.

Happening on 32bit iso as well.. as of 18/04/2018

on x64 version, I see a flash of the try or install screen before it goes straight to desktop..

This is the error

and the traps just before this trace

[ 28.900976] xubuntu kernel: traps: xfsettingsd[1491] trap int3 ip:7f8a4f9dfc41 sp:7fff2ddeac90 error:0 in libglib-2.0.so.0.5600.1[7f8a4f98e0

actually this trap is just because it cannot open a display

journal with the failure.

Reverting this patch makes ubiquity-dm appear.

@jibel - as far as I'm aware there is a merge from Steve Langasek for this? at least that was my impression when talking to him - https://bazaar.launchpad.net/~vorlon/ubiquity/conflict-with-getty1/revision/6609

This was fixed in ubiquity 18.04.6.

ubiquity (18.04.6) bionic; urgency=medium

  [ Steve Langasek ]
  * If we are running ubiquity-dm on VT1, we must conflict with
    <email address hidden> and not rely on some other display manager to do
    this for us.

  [ Brian Murray ]
  * Drop the option to upgrade from an old release using ubiquity as it is
    crashing and leaves users in a broken state. (LP: #1756862)

  [ litianzhi ]
  * Fix untranslated "This software is subject to license" (LP: #1762097)

  [ Mathieu Trudel-Lapierre ]
  * debian/real-po/, po/: Translations import from Launchpad.

jibel's logs show that this is still happening with ubiquity 18.04.6. reopening for another look.

The correct service name to conflict with is '<email address hidden>', not '<email address hidden>'. Fixing.

This bug was fixed in the package ubiquity - 18.04.7

---------------
ubiquity (18.04.7) bionic; urgency=medium
