Как я могу удалить Adobe acroread, когда ничто иное не работает?

Я проверил все подобные вопросы. Ни один из них не предлагает рабочего решения в моем случае. Это не дубликат. Вот детали моей уникальной ситуации:

$ acroread

Это заставляет Adobe Acrobat Reader 9 открываться и работать.

после выполнения этой последней команды acroread все еще установлен и ввод acroread при любой подсказке все еще заставляет это открываться и работать.
