Ubuntu Linux stands as a beacon of open-source excellence, offering a solid platform for developers, enthusiasts, and professionals alike. Central to its appeal is the ease of managing and updating software—a critical task for maintaining system security and performance. For those inclined towards the simplicity and power of the command line, Ubuntu provides a suite of tools that make this task both efficient and pleasant. In this blog, we will go through the different methods available for updating Ubuntu Linux software using the command line interface.
Why Update Using the Command Line?
The command line, or terminal, is a powerful tool that offers efficiency, precision, and the ability to automate tasks through scripting. For many, it has become a preferred method for managing software updates due to its speed and the granular control it provides over the update process.
Let’s now look at the steps involved in each method of updating Ubuntu Linux software.
Method 1 – Update with APT (Advanced Package Tool)
At the heart of Ubuntu’s package management system lies APT, a powerful tool that simplifies the process of managing software packages.
To Update with APT:
1. Refresh Your Package List
Before making any updates, it’s essential to refresh your local package list to ensure it aligns with the repositories. Use the command:
sudo apt update
This command retrieves the latest information about package versions and their dependencies without installing anything.
2. Upgrade Packages
With your package list refreshed, the next step is to upgrade the installed packages. This can be done with:
sudo apt upgrade
This command upgrades all the installed packages to the latest versions available from the Ubuntu repositories. It’s a safe operation, as it doesn’t remove any packages or install ones that aren’t already installed.
3. Dist-Upgrade for a Deeper Update
For a more thorough update that can handle changes in package dependencies and remove obsolete packages, use:
sudo apt dist-upgrade
This command is more aggressive but ensures your system’s packages remain in harmony, especially after significant updates.
4. Cleaning Up
After upgrading, it’s good practice to remove obsolete packages and clear the APT cache:
sudo apt autoremove
sudo apt clean
APT is the cornerstone of Ubuntu package management, providing a solid foundation for system updates and maintenance.
Method 2 – Update with APT-FAST
For those seeking to accelerate the update process, apt-fast is a wrapper script that employs multiple connections to fetch packages simultaneously, significantly speeding up the download process.
To Update with APT-FAST:
1. Installation
First, install apt-fast by adding its PPA (Personal Package Archive) and installing it:
sudo add-apt-repository ppa:apt-fast/stable
sudo apt update
sudo apt install apt-fast
2. Using APT-FAST
Like APT, start by updating the package list:
sudo apt-fast update
Then, proceed with upgrading packages:
sudo apt-fast upgrade
APT-FAST can significantly reduce the time required for updates, making it an excellent choice for users with slower internet connections or those who value speed.
Method 3 – Update with APTITUDE
APTITUDE is another alternative to APT, offering a text-based interface and additional features for handling packages.
To Update with APTITUDE:
1. Launch APTITUDE
If not already installed, you can install APTITUDE using:
sudo apt install aptitude
To update and upgrade packages, simply run:
sudo aptitude update
sudo aptitude safe-upgrade
APTITUDE provides a more interactive experience and offers detailed information about package dependencies.
Method 4 – Update with UNATTENDED-UPGRADES
For those who prefer a “set it and forget it” approach, unattended-upgrades allows for automatic installation of security updates.
Setting up UNATTENDED-UPGRADES:
1. Installation and Configuration
Ensure unattended-upgrades is installed:
sudo apt install unattended-upgrades
Configure it to automatically install updates by editing its configuration file or using interactive configuration tools.
2. Enable Automatic Updates
Enable and configure automatic updates through:
sudo dpkg-reconfigure --priority=low unattended-upgrades
This tool is particularly useful for maintaining the security of servers or unattended workstations.
