Questions[language-support](ubuntu)

I have recently updated Ubuntu to 18.04. After this, issuing the command ld constantly failed with the following assertion:

loadlocale.c:129: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.

I have googled this problem and it looks like this is a well known issue. All of the solutions that I have read suggested fixing this using the following command:

export LC_ALL=C

See, for example, this one. However, doing so breaks fonts of the commentaries on my native language in VIM for example.

So, this solution is not suitable for me-. Are there any other ways to fix this issue?

Just installed gscan2pdf v1.3.9 as well as Tesseract. As for the latter, first it appeared at the bottom of my Installed Software list, but now it seems to be gone, although still working (I think).

Anyway, I'm trying to turn a pdf of a scanned document into editable text, but the document is not in English, so gscan makes a mess out of it.

Only options I get when I go to Tools > OCR > Language to recognize is English, equ, and osd. Any ideas on how I can install a specific language pack?

I'm no experienced Linux user so step-by-step instructions would be greatly appreciated.

I want to switch to French locale. So I tried the below command:

myUbundu@myUbundu-desktop:~$ export LC_ALL=fr_FR

But I am getting the warning

-bash: warning: setlocale: LC_ALL: cannot change locale (fr_FR)

How to set the locale to French? Do I need to install additional packages?

How do I configure Ubuntu to input Chinese?

How do you switch Ubuntu to another (human) language without reinstalling it?
