[Bug 2070278] [NEW] selected language doesn't prompt missing language support after the offline installation

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

When the installer was run without an internet connection, selected
language during the installation may miss the language support packages
(as expected). In the previous installer (or previous versions of
Ubuntu), the language-selector prompted missing language support after
the initial installation so users had a chance to install those once the
system is connected to the internet. However, it's no longer the case
with the new installer (or the new Ubuntu versions).

How to reproduce:

1. Launch ubuntu-24.04-desktop-amd64.iso
2. Close the installer
3. Refresh the snap first
   $ sudo snap refresh ubuntu-desktop-bootstrap
4. [for the offline case] Disconnect from the network
5. Re-launch the installer
6. Select a language other than English, e.g. Japanese(日本語)
7. Continue the installation with default options
8. Reboot


Check the locale and the language support:

[online]

$ locale
LANG=ja_JP.UTF-8
LANGUAGE=
LC_CTYPE="ja_JP.UTF-8"
LC_NUMERIC="ja_JP.UTF-8"
LC_TIME="ja_JP.UTF-8"
LC_COLLATE="ja_JP.UTF-8"
LC_MONETARY="ja_JP.UTF-8"
LC_MESSAGES="ja_JP.UTF-8"
LC_PAPER="ja_JP.UTF-8"
LC_NAME="ja_JP.UTF-8"
LC_ADDRESS="ja_JP.UTF-8"
LC_TELEPHONE="ja_JP.UTF-8"
LC_MEASUREMENT="ja_JP.UTF-8"
LC_IDENTIFICATION="ja_JP.UTF-8"
LC_ALL=

$ check-language-support
<empty>

$ check-language-support -l ja
<empty>

-> expected as all language support is installed through the internet
connection in the installation phase


[offline]

$ locale
LANG=ja_JP.UTF-8
LANGUAGE=
LC_CTYPE="ja_JP.UTF-8"
LC_NUMERIC="ja_JP.UTF-8"
LC_TIME="ja_JP.UTF-8"
LC_COLLATE="ja_JP.UTF-8"
LC_MONETARY="ja_JP.UTF-8"
LC_MESSAGES="ja_JP.UTF-8"
LC_PAPER="ja_JP.UTF-8"
LC_NAME="ja_JP.UTF-8"
LC_ADDRESS="ja_JP.UTF-8"
LC_TELEPHONE="ja_JP.UTF-8"
LC_MEASUREMENT="ja_JP.UTF-8"
LC_IDENTIFICATION="ja_JP.UTF-8"
LC_ALL=


$ check-language-support 
<empty>

$ check-language-support -l ja
fonts-noto-cjk-extra gnome-user-docs-ja ibus-mozc language-pack-gnome-ja language-pack-ja

-> two output should be identical so the language selector can suggest
installing those missing packages. Otherwise, users may not know those
packages including language packs are available.
