La página de manual de apt-get es la siguiente:
NAME
apt-get - APT package handling utility -- command-line interface
SYNOPSIS
apt-get [-asqdyfmubV] [-o=config_string] [-c=config_file] [-t=target_release]
[-a=architecture] {update | upgrade | dselect-upgrade | dist-upgrade |
install pkg [{=pkg_version_number | /target_release}]... | remove pkg... |
purge pkg... | source pkg [{=pkg_version_number | /target_release}]... |
build-dep pkg [{=pkg_version_number | /target_release}]... |
download pkg [{=pkg_version_number | /target_release}]... | check | clean |
autoclean | autoremove | {-v | --version} | {-h | --help}}
El indicador -q o -qq debe ir antes del comando, así:
apt-get -qq upgrade
