apt-получить "не удается найти пакет" с glob

Я пытаюсь удалить рабочий стол Pantheon. Я использую Star glob для удаления всех пакетов с именем, которое начинается с "pantheon -".

rolf@DRGMC01:~$ sudo apt-get remove pantheon-*

E: Couldn't find any package by glob 'pantheon-debian-repos_0.4-0+pantheon+stretch+loki1_all.deb'
E: Couldn't find any package by regex 'pantheon-debian-repos_0.4-0+pantheon+stretch+loki1_all.deb'

OK, давайте установим отсутствующий пакет.

rolf@DRGMC01:~$ sudo apt-get install pantheon-debian-repos

нет.
Он действительно установлен?

rolf@DRGMC01:~$ dpkg -l |grep '^ii  panth'

  etc.

что здесь происходит?

• почему apt-get не видит установленный пакет?
• почему оно заботит о этом пакете на все?
