Japenese input method available (and sometimes selected?) by default on Hirsute images

[Iain Lane]

I just tried with today's daily, which is the first ISO image that contains ibus-mozc 2.26.4220.100+dfsg-4ubuntu2.

I noticed that an 'A' was displaying next to the input indicator (the 'A' seems like a bug in itself!). Clicking that showed me that this is because Japanese was selected. It's possible though that I hit something which switched input language. Picture attached.

Japanese shouldn't be available for everyone by default; I think there's a bug in the new mozc which means that it is. I checked with the previous ISO (20210316) that has the old mozc and this bug isn't present there.

Gunnar, if you're seeing this, any chance you can help us look into this bug please?

Yep, all Ubuntu users are expected to input Japanese from now on. :)

More seriously, I have not seen it yet, but it's most likely caused by the fix of <https://bugs.debian.org/983623>. They have added an autostart script in order to make ibus-mozc available out of the box at first login in case of a Japanese install of GNOME.

I thought it wouldn't affect us adversely. We don't use tasksel, and handle those things via a gnome-settings-daemon patch. But apparently I overlooked Ubuntu's live session in combination with ibus-mozc being shipped on the ISO.

I'll fix it somehow. Hopefully in a way that won't cause an Ubuntu/Debian delta.

Thanks! That fix sounds likely, if just starting ibus-mozc is enough to
get it made available and it doesn't inspect the settings on the system.

I don't know if this is appropriate (if it wouldn't break input for
people who do want to type Japanese) or if mozc should be fixed to look
at the settings or something, but I just want to point out that we can
disable particular autostart services in the live session by shipping
hooks in the casper package. There are a few examples in there already
if you grep for "autostart".

Well, it does inspect the settings. If you would run a Chinese live session, you wouldn't see ibus-mozc since there is already another IBus IM enabled. But if there is no IBus IM, and ibus-mozc is installed (which it always is in the live session), then it gets auto enabled.

The underlying assumption is that if you install ibus-mozc you want to use it. But that assumption doesn't take Ubuntu's ISO into account.

Thanks for the tip, will have a look. If that can be done without disabling the gnome-settings-daemon mechanism for adding input methods (which I suppose it can), it wouldn't break anything in case of a Japanese live session.

The casper route looks right to me, and I submitted a merge proposal. Added a script using 52gnome_initial_setup as a template.

Any chance you can sponsor?

This bug was fixed in the package casper - 1.461

---------------
casper (1.461) hirsute; urgency=medium

  * scripts/casper-bottom/59disable_mozc_autosetup:
    - Don't set up ibus-mozc automatically in non-Japanese sessions
      (LP: #1919455)

  * Add a gbp.conf so --git-tag{,-only} works

Follow-up
---------
Played with today's daily ISO and confirmed that
- ibus-mozc is not enabled in an English live session
- ibus-mozc is enabled in a Japanese live session
- the mozc packages are removed when completing an English install
