Atom: Cannot load the system dictionary for en_IN. Checked the following paths for dictionary files:

I have resolved this problem using language update in editor following way:

1) Atom → Edit → Preferences → Packages

2) search for "spell check" and deselect Use Locales button and mention en-US (editor support language) in custom bar.

3) After restart the editor.

You might be missing the system dictionaries.

Go to settings with ctrl-, and look in Packages for the package spell-check. Enter its settings.

Make sure Use Locales is selected (default, I believe).
Write the necessary locales in the Locales box, for example en_US, pt_PT would work for both American English and European Portuguese. This is useful for those who write in multiple languages.
Install the necessary dictionaries on your system. In this case that would be:
```
$ sudo apt install hunspell-pt-pt hunspell-en-us`
```
