имя ppa для ppa-purge

Я знаю, что существует тот же вопрос, но я думаю, что в этом вопросе нет ответа. Я должен очистить некоторые ppas, и я пытаюсь использовать ppa-purge с этой командой:

sudo ppa-purge ppa:<ppa_name>/ppa

Но что это ppa_name? У меня это (плохое) sources.list.d

danielrichter2007-grub-customizer-precise.list       google-chrome.list.save                      n-muench-vlc-precise.list                 videolan-stable-daily-precise.list.save

Но я не знаю имени, например:

sudo ppa-purge ppa:lubuntu/ppa
Updating packages lists
PPA to be removed: lubuntu ppa
Warning:  Could not find package list for PPA: lubuntu ppa
