/ var / lib / использую большую часть своего пространства

У меня есть Digital Ocean VPS с 2 ГБ ОЗУ, 50 ГБ пространства и 1 виртуальным ЦП. Запуск Ubuntu Server 20.04 LTS

Тем не менее, у меня осталось всего 16 ГБ. Изучив это дальше, я обнаружил, что мой каталог / var / lib использует 22 ГБ. Тем не менее, когда я заглядываю в эти папки, я не вижу файлов, которые занимают такой объем места.

Это работает LAMP для установки Wordpress. У меня две виртуальные живые. Каталог / var / www занимает всего 6 ГБ, и я могу все учесть.

Есть какие-либо мысли о том, почему это происходит и как исправить?
