kde-l10n-zhcn depends on ibus-pinyin

Bug Description

Kubuntu 13.04/KDE 4.10.3

 kde-l10n-zhcn Version 4.10.3-0ubuntu1~ubuntu13.04~ppa1

What I wanted to do:
Uninstall package ibus (IME), ibus-pinyin, ibus-pinyin-db-open-database, pinyin-database, python-ibus, libibus-1.0.0

What instead happened:
4.10.3-0ubuntu1~ubuntu13.04~ppa1 depends on package ibus-pinyin. Uninstalling ibus doesn't work, only if uninstalling kde-l10n-zhcn as well as languagepack-kde-zh-hans.

Does that make sense? I use fcitx and there are more IME around. So I don't need ibus as far as I understand. Could that be changed?

Thank you!

///// Also affect latest version 14.04 Kubuntu LTS

This is unacceptable that kde-l10n-zhcn has a dependency of ibus-pinyin, because for Chinese end-users, they do have choices to install what input method they like.

So pls pls pls pls pls pls pls remove the dependency of "ibus-pinyin"

It's NO REASON for a language pack to depend on an input method, I'm a fcitx user and I won't use Kubuntu only because of the dependency of "ibus-pinyin". Users do have choices to install what input method they like. For vivid, this may lead to multiable input methods installed together by default because vivid uses fcitx as default input method.

So pls pls pls pls pls pls pls remove the dependency of "ibus-pinyin"!

I have heard of some rumors that the ibus-pinyin package is deprecated and may soon be removed from repository (both in debian and ubuntu). This package may fail if still declares the dependency to ibus-pinyin.

As a result, please fix this problem ASAP to avoid further problems.

Now it is Dec. 2016 and I would again remind everyone that this is still a bug that exists from 2013 to 2017.

This has long been a blocking issue. Every Chinese Kubuntu user has to bear the whole ibus inside the system which is totally useless and would interfere with any other input method. I'm sure that lots of users have given up using Kubuntu due to this annoying issue. If it does not get fixed, more will.

It is June 2018 now, and the problem is still unsolved.
It's really annoying.
The problem is, for example, the DVORAK keyboard you use, but when you install kde-l10n-enus (if exist), the keyboard layout must be QWERTY.

To fix the bug, just remove


in substvars. It's really hard?

I wonder if it is an easy change to make kde-l10n-zhcn not depending on ibus as preset.

The problem might be if somebody installs a system based on kde-l10n-zhcn and there is no preset IME then there is no input possible in Chinese but only in English. Many Chinese people don't speak English, at least for them it would be difficult to use the fresh installed system, before add an IME.

I am not aware of a method to make kde-l10n-zhcn dependend on a chooseable IME, where one method is obligatory and at least all IME with a bigger userbase would be available. So the discussion at the moment could only be if that should be changed to another IME, because more people are using it or because one is better than another.

However this could be integrated in system installers of course, like choosing the language or keyboard layout and should be if the userbase of Chinese speaking Linux users is big enough to find developers who would do this quite big task, as this would have to be added to quite a lot of distributions than.

I think this is the reason this "bug" isn't changed. In my Manjaro installation kde-l10n-zhcn installs only libibus as dependency, I can't uninstall it. I use fcitx, so I have an unused software of ~48 MiB - not such a big problem today. Even if I would prefer an integration in system installers.

  Here is my suggestion. The default would always be ibus, but it would then be possible to remove ibus and install fcitx or scim instead, and still keep kde-l10n-zh.

  In DEBIAN/control, change
Depends: ibus-pinyin
Depends: ibus-pinyin | ibus-libpinyin | fcitx-pinyin | fcitx-googlepinyin | fcitx-libpinyin | fcitx-sunpinyin | scim-pinyin
  to allow using another IME, the default one being the first one listed.

  Another refined way that would need a bit more work is to change
Depends: ibus-pinyin
Depends: ibus-pinyin | im-pinyin
  and add in all DEBIAN/control of ibus-pinyin, ibus-libpinyin, fcitx-pinyin, fcitx-googlepinyin, fcitx-libpinyin, fcitx-sunpinyin and scim-pinyin
Provides: im-pinyin
  The default still being ibus-pinyin.
