Как удалить PlayOnLinux? (Удаление программного обеспечения Ubuntu не работает)

Я иду в Ubuntu Software, ищу playonlinux и затем нажимаю remove:

Это делает это .. .

Затем все еще показывает мне, что он установлен. Также после перезагрузки и ожидания 10 часов.

Что я могу сделать?

Планирует ли Canonical обеспечить нормальную работу утилиты установки / удаления программного обеспечения в 2018/2019 году? Кто-нибудь знает, есть ли что-то подобное в их дорожной карте? Могу ли я где-нибудь увидеть дорожную карту?

ОБНОВЛЕНИЕ:

При выполнении sudo apt remove playonlinux происходит следующее:
