** Description changed:
Package: gnome-initial-setup 50.0-0ubuntu7.1 (Ubuntu 26.04 LTS)
[ Impact ]
When there is no network connection, the last page of the welcome wizard
shows "All done!" with the "Downloading additional language packs"
spinner and a "Cancel Download" button, forever. Nothing is downloading.
The "Start Using Ubuntu" button only appears after the user clicks
"Cancel Download".
In gnome-initial-setup/pages/summary/gis-summary-page.ui, download_box
is the first child of status_stack, so the stack shows it by default.
gis_summary_page_shown() only touches the stack when
check_network_connection() returns TRUE; the offline branch never
switches status_stack to start_box.
This hits every offline first boot: OEM installs, machines without
Ethernet whose Wi-Fi is not set up yet, and unattended installations
from the Desktop ISO.
gnome-initial-setup 51.0-0ubuntu1 in stonking already fixes it:
start_box is the first child of status_stack since commit 2bf4b186
("d/p/u: Rework dynamic-lang support for new async save_data") on the
ubuntu/latest branch of https://salsa.debian.org/gnome-team/gnome-
initial-setup. The ubuntu/resolute branch (50.0-0ubuntu7.1) does not
have it. That commit reworks the patch for the new async save_data of
51, so only its reordering of the two children in gis-summary-page.ui
needs a backport to resolute.
[ Test Plan ]
- 1. Install Ubuntu 26.04 Desktop in a VM without a network card (for example
QEMU with "-nic none").
+ 1. Install Ubuntu 26.04 Desktop with the following autoinstall in a VM
+ without a network card (for example QEMU with "-nic none"), so that no
+ user is configured and the welcome wizard runs at first boot:
+
+ autoinstall:
+ version: 1
+ source:
+ id: ubuntu-desktop-minimal
+ storage:
+ layout:
+ name: lvm
+ user-data:
+ users: []
+
2. At first boot, go through the welcome wizard until the last page.
+
3. Expected: "All done!" with the "Start Using Ubuntu" button.
- Actual: "All done!" with the "Downloading additional language packs"
spinner and "Cancel Download", which never ends.
- 4. With the fixed package, step 3 shows the "Start Using Ubuntu" button right
away. With a network connection, the language pack download runs as before.

[ Where problems could occur ]
The change only reorders the two children of status_stack in the summary
page UI file. The online path sets the visible child explicitly, so it
should not change. A regression would show as the wrong box on the
summary page: the start button while language packs are downloading, or
the spinner after the download is done.
[ Other Info ]
Seen during unattended installations of the Ubuntu 26.04.1 Desktop ISO
with no network. journalctl shows that no check-language-support or apt-
get process is started: only the UI is stuck.
