Lubuntu 20.04 Writer Spell Checker NOT Working

Refer: https://askubuntu.com/questions/1150144/spell-checker-not-working-in-libre-office-6-0

File: dict-en-20200601.7z

This worked for me. Even hunspell or myspell, as suggested by resplin, didn't work.

However adding this extension to Libre Office worked like charm: https://extensions.libreoffice.org/extensions/english-dictionaries/

You'll need to go to Tools > Extension Manager > Add > {upload extension file}. Restart.

Adding spell-check to nano, you can invoke by Ctrl+T

$ sudo nano /etc/nanorc

And uncomment the following line:
set speller "aspell -x -c"
