# Configure any packages which have been unpacked but not configured, as otherwise --fix-broken might fail
# However, package configuration can also fail due to dependency issues that would be fixed by --fix-broken
# so if the command fails, try to run --fix-broken
dpkg --configure -a || apt-get --assume-yes --fix-broken install
# Attempt to fix broken or interrupted installations
# If this fails, try to configure any packages which have been unpacked but not configured
apt-get --assume-yes --fix-broken install || dpkg --configure -a
apt-get --assume-yes dist-upgrade # Upgrade all packages, and if needed remove packages preventing an upgrade
apt-get --assume-yes autoremove # Remove packages only installed as dependencies which are no longer dependencies
apt-get --assume-yes clean # Remove local repository of retrieved package files

Beskrivelse

Dettte script opdaterer alle pakker på systemet “her og nu”.

Så det anbefales at køre dette script hvis en opdatering ude på maskinen er gået galt, eller hvis man kun har sat automatiske sikkerhedsopdateringer til.

Da scriptet involverer overførsel af meget data kan det i nogle situationer godt fejle, hvis der i opdateringsperioden opstår netværksproblemer lokalt eller hos de servere, der opdateres fra. Oplever du fejl, kan det derfor godt anbefales at prøve at køre scriptet én gang til.

Dette script er blevet testet og virker på Ubuntu 22.04.
