Set Ubuntu20.04server as GUI and Mozc to Japanese keyboard setting

I installed Ubuntu20.04server, but I needed a setting that would improve usability, so I will write down the knowledge I learned at that time.

Make the interface GUI

Immediately after installation, only CUI can be used. As expected, it is difficult to use without a GUI, so I would like to include a GUI. To do this, run the following command.

python

$ apt install ubuntu-desktop

Make Mozc a Japanese keyboard

When I changed the Japanese input to Mozc, it became an English keyboard for some reason and it was difficult to use. I would like to change this to a Japanese keyboard. To do this, run the command below to open the Mozc config file.

python

$ vi /usr/share/ibus/component/mozc.xml

Rewrite default on line 19 of this file (in my environment) to jp.

  <layout>default</layout>
          ↓
  <layout>jp</layout>

After this, restart Ubuntu. Only this.
