Удаленный snapd с базовыми системными приложениями

После установки Ubuntu 18.04 я заметил широкополосный трафик с процессом snapd и так как я не использую поспешные приложения, я решил удалить снимок.

Я использовал эту команду $ sudo apt purge snapd ubuntu-core-launcher squashfs-tools

и это - вывод

Я заметил, что это удалило базовые системные приложения. Как я могу отменить процесс снова для восстановления снимка и тех приложений снова.

заранее спасибо
