No boards found linux

[thelastprime]

Hi,

I just installed Stino on ubuntu in sublime text 3. I see arduino in the toolbar, but no boards show up under boards. My settings are:
{ "additional_app_path": "/usr/share/arduino", "app_dir_path": "{$default}", "sketchbook_path": "{$default}" }

I'm running ubuntu 17.04 in a chroot on a chromebook.

Thanks!
