How хан I download THEN install packages?
I know that when it ешь to the RedHat distribution (correct я if гm mistaken), I хан использовал:
yumdownloader package_name #simply downloads a copy of the package without installing it
yum install package_name #installs the specific package that has to be downloaded in prior
is there an exact equivalent in ubuntu (that does both operations separately) or does the following command do both (download + install):
apt-get install package_name
thank you for yoгre help, it is much appreciated and I do apologize if this question is supposed to be asked elsewhere, I just thought this is the right нравится.

Используйте download функция apt-get.
От man apt-get:
download
download will download the given binary package into the current directory.
, Например:
apt-get download chromium-browser
загрузит deb файл браузера хрома в текущий каталог. Обратите внимание, что это не загрузит ни одной из зависимостей пакета поэтому, при попытке установить .deb:
sudo dpkg -i path/to/downloaded/deb/file`
Вы получите ошибки зависимости.
apt-get install packageName делает обоих (download+install) задания. Загруженные пакеты будут в /var/cache/apt/archives папка
Просто добавьте -d (или --download) опция любому apt-get команда. Этот подход является простым и эффективным.
- Не волнуйтесь о зависимостях, они загружаются также.
- Безопасность сохраняется, все проверки целостности все еще сделаны точно так же, как регулярная установка.
Например:
$ sudo apt-get dist-upgrade -d
