What to do if Japanese language support is not completely installed on Ubuntu 16.04
As of April 2020, most people are using Ubuntu 18.04 LTS, but there are still many software development environments that recommend Ubuntu 16.04 LTS. So, when I installed Ubuntu 16.04 on my PC the other day, the state immediately after installation was "incomplete Japanese support". Make a note of the steps to complete Japanese localization.
This procedure is the operation method when using the GUI tool.
Setup steps
Package installation
--Open System Settings and click Language Support.
--The message "The Language support is not installed completely" appears.
--Click "Install".
--Installation may require administrator privileges.
--The package will be installed automatically.
--Click the "Language Support" window after the installation is complete.
--Drag and drop the Japanese of "Language for menus and windows" to the top.
--Click "Apply System-Wide" to apply to the entire system
--You will be asked for administrator privileges, so enter it to reflect it.
Reboot
Reboot the system for the changes so far to take effect. You can log in and out, but if you log in and out at the same time for all users and background tasks, it will not be reflected later, so restart it.
Rename home directory
--After rebooting, you will be asked if you want to change your home directory name.
--In Linux, if the directory name has Japanese, use English notation, which is troublesome to operate.
--Here, check "Do not show again" and click "Keep old name".
If it is confirmed in the directory with the Japanese name
You can change it to an English name with the following command. `LANG = C``` is the base language (English) that never changes in the system. You can translate your home directory name into English by running the directory name change tool `xdg-user-dirs-gtk-update``` as a set.
$ LANG=C xdg-user-dirs-gtk-update
Summary
It's not a big change, but if these things don't match, you'll lose a little time when doing remote work, saying "No such message" or "No such directory". I will summarize it carefully.
