apt-get update
memperbarui daftar paket yang tersedia dan versinya, tetapi tidak menginstal atau memutakhirkan paket apa pun.
apt-get upgrade
sebenarnya menginstal versi lebih baru dari paket yang Anda miliki. Setelah memperbarui daftar, manajer paket mengetahui tentang pembaruan yang tersedia untuk perangkat lunak yang telah Anda instal. Inilah mengapa Anda pertama kali menginginkannya update

Ketika teman Anda menyebut pembaruan sebagai "perubahan kecil" dan meningkatkan sebagai "perubahan besar" ia sebenarnya berarti perbedaan antara peningkatan dan dist-upgrade .
Dari manual apt-get:
upgrade
upgrade is used to install the newest versions of all packages
currently installed on the system from the sources enumerated in
/etc/apt/sources.list. Packages currently installed with new
versions available are retrieved and upgraded; under no
circumstances are currently installed packages removed, or packages
not already installed retrieved and installed. New versions of
currently installed packages that cannot be upgraded without
changing the install status of another package will be left at
their current version. An update must be performed first so that
apt-get knows that new versions of packages are available.
dist-upgrade
dist-upgrade in addition to performing the function of upgrade,
also intelligently handles changing dependencies with new versions
of packages; apt-get has a "smart" conflict resolution system, and
it will attempt to upgrade the most important packages at the
expense of less important ones if necessary. The dist-upgrade
command may therefore remove some packages. The
/etc/apt/sources.list file contains a list of locations from which
to retrieve desired package files. See also apt_preferences(5) for
a mechanism for overriding the general settings for individual
packages.
