Issue of locale setting (Traditional Chinese) when installing Lubuntu 22.04.01

In the newest 22.04.01 LTS version, I got a exclamation mark during installation when the system automatically detected my area and chose “Traditional Chinese” “lzh_TW”. The information is
“Warning: No translation found for languages (“lzh_TW”, “lzh”)”. After installation, the Lubuntu desktop is in English mode, and even if I changed the language in the “Locale” setting to “Traditional Chinese” “lzh_TW”, several (but not all) of the texts in Apps or icons remained in English instead of Chinese. What’s more, every time I upgrade an application, I got the following messages

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "",
        LC_ALL = (unset),
        LC_TIME = "zh_TW.UTF-8",
        LC_MONETARY = "zh_TW.UTF-8",
        LC_COLLATE = "zh_TW.UTF-8",
        LC_ADDRESS = "lzh_TW",
        LC_TELEPHONE = "lzh_TW",
        LC_NAME = "lzh_TW",
        LC_MEASUREMENT = "zh_TW.UTF-8",
        LC_IDENTIFICATION = "lzh_TW",
        LC_NUMERIC = "zh_TW.UTF-8",
        LC_PAPER = "lzh_TW",
        LANG = "zh_TW.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

I don’t remember I have such an issue when installing Lubuntu using
the 22.04 LTS iso file, but for unknown reason the old 22.04 iso is no longer available everywhere. I wonder if this is a bug and could be fix in the future upgrade? Thank you very much.


Looks very similar to this.


Sounds like an installer bug. I will try to reproduce this and help fix it.

When you installed from the original 22.04 ISO, did all of the application names display in Chinese? Knowing this may be helpful.

If you need an original 22.04 ISO, you can still download it from the Internet Archive here:


Dear Arron,

Yes. I have confirmed that this issue exists on 22.04.01 only. When installed by 22.04 iso, all the applications display correct Chinese and no warning has been reported during the installation.
