Software packages for Linux distributions, especially Debian and Ubuntu, can be installed, updated, and managed with the help of APT (Advanced Packaging Tool). With APT, you can easily update to the latest versions of available packages. The apt-get update vs apt-get upgrade commands are frequently used in APT package management. Many Linux users are unfamiliar with the apt-get update vs apt-get upgrade commands, despite their frequent use. Although they have distinct purposes, some people treat them as interchangeable. In this article, we’ll look at the differences between Sudo apt-get update vs apt-get upgrade. Enjoy the ride!
What Is Apt-Get Update?
When a new piece of software is being installed, or after a fresh system install, this command is typically used. The apt-get update command refreshes the Linux system’s package index, or package listings. Some Linux users are under the impression that it upgrades packages when, in fact, it does not. The /etc/apt/sources.list file defines software repositories that can be accessed through the package index file. You can find other package lists in the /etc/apt/sources.list.d folder. This command can be executed with complete confidence. If it has to be interrupted for any reason, you can pick up right where you left off.
How Does Sudo Apt-Get Update Work?
Each Linux package has its own record on the system, detailing its installation and its contents. With the “apt-get update” or “apt update” command, the system checks for updated packages and installs them if necessary. Executing this command retrieves the most recent package data as detailed in the source file.
What Is Apt-Get Upgrade?
Do you need to update to the most recent version of your software? Then the command to use is apt-get upgrade. When run without any parameters, the apt upgrade command updates all out-of-date packages on your machine to the most recent stable release. The command also initiates the installation of new packages if they are required due to dependencies. In addition, an apt-get upgrade will apply any critical security updates to your system, further strengthening its defenses. You can see what packages can be upgraded by typing “apt list –upgradable” into a terminal. As a matter of fact, this is a hint that appears on the final page of the apt-get upgrade output.
How Does Sudo Apt-Get Upgrade Work?
If you’ve already installed a package and want to update it to the most recent version using the data you gleaned from an earlier “apt-get update” or “apt update” command, you can do so using the “apt-get upgrade” command. This command does not install any new packages, simply upgrades previously installed ones.
The “apt-get update” command should be executed before the “apt-get upgrade” command to guarantee that your system has the most recent information about available package updates.
Apt-Get Update vs Apt-Get Upgrade
The key distinction between apt-get upgrade vs apt-get update is that apt-get update pulls the list of packages to update from all of your software repositories, not just the ones you installed yourself. However, new and updated packages are installed and upgraded throughout the apt-get update process.
Apt-get upgrade vs Apt-get update: Differnces
In Linux, there are two commands that install packages: apt-get update vs apt-get upgrade. Using the apt-get update command, the system’s package index files (which list available packages and their versions) are brought up-to-date. It fetches the most up-to-date package data from the locations specified in the “/etc/apt/sources.list” file. To make sure your system has the most recent package updates, you should execute apt-get updates on a regular basis.
To upgrade to the most recent version of already installed packages, however, use the apt-get upgrade command. The command “apt-get update” is used to determine which packages should be upgraded. By downloading and installing the most recent packages, “apt-get upgrade” updates your system to the latest version.
The difference between apt-get update vs apt-get upgrade boils down to the fact that the former refreshes the package index files while the latter upgrades the packages already in use. To ensure that your Linux installation has the most recent updates installed, you must use apt-get update vs apt-get upgrade.
Apt Update vs. Apt Upgrade: A Comparison
If you’re using Linux, updating your packages may seem as simple as running the apt-get update command. While the update command will inform you of any available updates, it will not actually download or install them for your distribution. However, the apt-get upgrade command pulls down and applies all available updates to your machine simultaneously. There is a repository of packages (software) on your Linux system, along with all the accompanying metadata. Version, repository, dependence, and other package-specific information can all be found in the metadata.
You won’t know about available package updates unless you run the update command to refresh the cache.
The apt update command is explained below.
sudo apt update
- It is common practice to immediately follow the update command with the upgrade command, which performs the actual download.
sudo apt upgrade
- When you tell APT to upgrade, it will immediately start downloading the necessary files. A confirmation window will appear, asking you to approve the download and installation. To confirm, press the y key or click yes.
- You can also change the upgrade command so that the packages download and run without stopping.
sudo apt upgrade -y
- The -y option gives APT the necessary installation confirmation.
- At long last, you can combine the apt-get update vs apt-get upgrade procedures into a single operation. Together, they trigger an instantaneous cache refresh, download, and installation of any available updates.
sudo apt update && sudo apt upgrade -y
- The && operator joins the two instructions, and then -y provides a default confirmation to apt-get upgrade vs apt-get update your packages.
Selecting the Appropriate System Command
Your system’s needs and the degree of control you want over package management will determine which of the two commands, ‘apt-get upgrade’ vs ‘apt dist-upgrade’ is the best fit.
The ‘apt upgrade’ command is the one to use if you’re averse to change and want a more cautious approach. To avoid unintentionally installing or uninstalling other packages, this program will only upgrade those that can be securely updated.
However, ‘apt dist-upgrade’ should be used if a more thorough upgrade is required, one that takes into account complex dependency changes. This tool allows for trouble-free package updates, even when introducing new dependencies or resolving package conflicts.
Notes about Apt Upgrade Commands’ Safety and Caution
Always have a recent backup of your system before running ‘apt upgrade’ or ‘apt dist-upgrade’. This safeguards data and functionality in the event of upgrade complications. Also, before moving forward with the upgrade, check the list of modifications. That way, you can anticipate and prevent any software-related problems that might arise.
Knowing How to Use the apt list –upgradable Command
Like the update command, the apt –upgradable option lists all the packages that can be updated. It’s important to note that the update command does not provide a list of available updates; it merely updates the package cache.
Unlike the upgrade command, the –upgradable option does not download or install the necessary packages. Instead, you can check out the updated packages and decide whether or not to install them.
In the terminal window, input the following to view a list of all the upgrades:
sudo apt list --upgradable
The aforementioned command will not display the available updates for other package managers, such as Flatpak, Snap, or any others, if they are installed on your system. Only APT packages will function.
You need to also know that the APT package manager is only compatible with Ubuntu and other distributions based on the Debian system.

Why You Need Apt-Get Update vs Apt-Get Upgrade
Regular usage of both apt-get update vs apt-get upgrade is recommended to keep your system secure and up-to-date. While ‘apt update’ refreshes the local package index to reflect the most recent versions of available software, ‘apt upgrade’ actually applies those packages to your system.
What Is Apt-Get Install Used For?
To manage packages in Linux, use the apt-get command-line program. To install, upgrade, or remove packages and their dependencies, it must first acquire the necessary information and packages from authorized sources.
Should I Use the Apt-Get Upgrade or Full Upgrade?
For those who value stability over potential disruptions, ‘apt update’ is the way to go. Packages that may be securely upgraded without installing or uninstalling other packages will be upgraded using this command.
How Do I Upgrade Apt in Ubuntu?
Here is how to upgrade apt in Ubuntu:
- Open the terminal application.
- For the remote server, use the ssh command to login.
- Fetch the updated software list by running the sudo apt-get update command.
- Update Ubuntu software by running the sudo apt-get upgrade command.
- Finally, reboot the Ubuntu box by running the sudo reboot command.
What Are Sudo and Apt-Get?
Both sudo apt-get update and sudo apt-get upgrade consist of the same three parts: sudo, apt-get, and update or upgrade. Using the “superuser do” command, or “sudo,” you can execute software with administrative capabilities.
However, if you type sudo reboot followed by your administrator password, you will execute the reboot command in superuser mode, which will cause the system to restart. Also, apt-get is a package management and installation utility in Debian and other Linux distributions based on Debian.
Where Do Sudo Apt-Get and Sudo Apt Differ from One Another?
When it comes to Debian and its derivatives, apt is the superior program installer and manager. To update your system’s package list, you can use either sudo apt update or sudo apt-get update, as they are functionally the same.
The primary differences are that apt is easier to type, produces more helpful output, and has user-friendly features like a progress bar during package installation.
Is It Safe to Use Apt-Get Update vs Apt-Get Upgrade?
It is safe to use the apt-get update vs apt-get upgrade commands on Debian and other distributions based on Debian. Due to the infrequent nature of distribution upgrades and major package/dependency updates, this is the case. However, unlike with cutting-edge distributions like Arch Linux, you may have to put in some extra effort to use the latest version of a program. Installing from a PPA repository, using Snap or Flatpak, or compiling the program from source code are all viable options.
Can You Chain the Apt-Get Update vs Apt-Get Upgrade Commands?
Performing a sudo apt-get update, waiting for it to finish, and then performing a sudo apt-get upgrade may seem like a lot of work. However, while apt-get update vs apt-get upgrade are rather fast, it is often more convenient to perform a series of tasks and then return to them after a few minutes.
What Are Sudo Apt-Get Dist-Upgrade vs Sudo Apt Full-Upgrade, and Are They Safe to Use?
Under the hood, both commands perform the same function by updating obsolete packages and selectively removing them. They function similarly to a combined version of the commands sudo apt-get upgrade and sudo apt autoremove. It should be safe to run these commands. The upgrade is less harmful since it gives you more time to examine pending changes and because it never removes packages.
Apt-get update vs apt-get upgrade are vital tools for keeping your Linux installation up-to-date and secure. Although they share certain similarities in appearance, each serves a unique purpose and is often employed in tandem with the other. In order to keep your system up-to-date and working properly, you need to be familiar with these commands and the distinctions between them.
Also, to ensure that your system’s package lists are always up-to-date, you can use the apt-get update command. It updates your system’s PPA and repository package lists to the most recent versions available. However, when you run the command apt-get upgrade, it will update all of your packages to the most recent version and install any missing dependencies. It does not remove any packages and will not remove any that are scheduled for removal.
