[BPO] Backport mozc from lunar to jammy

[Gunnar Hjalmarsson]

[Impact]

The main reason for this backport proposal is to deal with the fact that bug #1931554 was not fixed in jammy. The bug was fixed in kinetic through a new upstream release, but fixing it as an SRU by cherry picking from upstream would be too complex.

To further justify the backport, I'm aware of at least one new feature. :) In the backported version the user can configure mozc to start in Hiragana mode instead of direct input mode which is the default.

[Scope]

The proposal is to backport mozc 2.28.4715.102+dfsg-2.2 from Ubuntu 23.04 to Ubuntu 22.04.

[Other Info]

Reverse dependencies
--------------------
task-japanese-desktop recommends uim-mozc and mozc-utils-gui, and task-japanese-gnome-desktop recommends ibus-mozc. Neither very relevant from an Ubuntu POV. No other reverse dependencies in relation to packages built by other source packages but mozc.

OTOH it may be worth mentioning that ibus-mozc, mozc-data and mozc-server are included in the Ubuntu ISO and installed by default in case of a Japanese install.

Reverse build dependencies
--------------------------
None.

The proposed package was uploaded to this PPA:

https://launchpad.net/~gunnarhj/+archive/ubuntu/mozc

It built successfully, and I have also confirmed that ibus-mozc with dependencies installs fine and seems to work as expected.

I uploaded mozc 2.28.4715.102+dfsg-2.2~bpo22.04.1 to the jammy backports queue.

[Launchpad Janitor (janitor)]

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

[Gunnar Hjalmarsson (gunnarhj)]

Is there any backporter around to consider this?

[Thomas Ward (teward)]

I give this a provisional ACK but want to check with mapreri or ddstreet first for a second ack before handling.

[Mattia Rizzolo (mapreri)]

I don't feel strongly against this, so I'm accepting this.

It is kind of out of line with what we normally like, however.

Thanks!
