To disable this update check for the Guest Additions of a given virtual machine. Other lists of packages are located in the /etc/apt/. The idea is that apt-get upgrade only upgrades individual packages, whereas apt-get dist-upgrade upgrades the whole distribution. The package index file is a file or database that contains a list of software packages defined in repositories located in the /etc/apt/sources.list file. It does not upgrade any packages, as some Linux users are misled to believe. The apt update command updates the package index of a Linux system or package lists. This is a command that is mostly invoked after a fresh system install or before installing a new software package. The indexes of available packages are fetched from the location(s) specified. apt upgrade is the command used to download and apply any available updates to your packages in a safe manner by not removing packages that are previously installed in a given Linux system, while apt full-upgrade command is used to do the same thing except if needed previously installed packages are removed to make the upgrade happen. sudo apt-get update sudo apt-get install .For example, a user on Ubuntu 16.04 LTS can upgrade to Ubuntu 18.04 LTS, but cannot jump directly to Ubuntu 20.04 LTS. Upgrade paths Ubuntu supports the ability to upgrade from one LTS to the next LTS in sequential order. Whereas the apt update process actually upgrades and installs new and existing packages. update update is used to resynchronize the package index files from their sources.

Difference between apt update and upgrade In this guide, we seek to distinguish the differences between sudo apt update and sudo apt upgrade. For some, these play the same role, which is not the case. upgrade (apt-get(8)) upgrade is used to install available upgrades of all packages currently installed on the system from the sources configured via sources. Let's have a look at its syntax through some realistic case studies of this mechanism.The apt update and upgrade are two of the most commonly used yet misunderstood commands for many Linux users. It also gives the name of the distribution (usually Stable, Testing, Unstable or Experimental for the standard distributions provided by Debian) together with its version (for example, 11 for Debian Bullseye). It specifies the origin (usually âDebianâ for the packages of official mirrors, but it can also be a person's or an organization's name for third-party repositories). ![]() Every package source is identified by the information contained in a Release file that APT downloads together with the Packages files. The available selection criteria include the package's name and the source providing it. Overview The Advanced Packaging Tool (APT) is a high-level package management tool for the Debian Linux distribution and its derivatives. Apt-get dist-upgrade has a smart conflict resolution system, so it will attempt to upgrade the most important packages, at the expense of those deemed less important. If several generic entries exist, the first match is used. When APT checks /etc/apt/preferences and /etc/apt/preferences.d/, it first takes into account the most specific entries (often those specifying the concerned package), then the more generic ones (including, for example, all the packages of a distribution). ![]()
