Как правильно освободить место в моей файловой системе /var/lib/snapd, когда snapd недоступен?

Я использую Ubuntu 20.04 LTS.

Мой сервис snapd недоступен:

$ systemctl status snapd.service
● snapd.service - Snap Daemon
     Loaded: loaded (/lib/systemd/system/snapd.service; enabled; vendor preset: enabled)

Как я могу правильно освободить место в моей файловой системе /var/lib/snapd, когда snapd недоступен?

EDIT0: Не удается успешно запустить службу snapd, возможно, из-за моего /var/lib/snapd файловая система заполнена.
