In my current instance of
Ubuntu 18.04 LTS, I have a bug of not having the
English Intl with Dead Keys option in the Language packages (in my VM it actually does appear) and I haven't been able to find it anywhere, be it from the
+ sign or any other advanced settings.
The steps I took to encounter this problem were:
Go to the
Region and Language Settings, press the
+sign, click on
English (US)(I've also tried it with other English countries), choose
English (US, intl. with dead keys).
Is there a way of reinstalling the English language package that includes the
Dead Keys options for sure?
