How to find and remove unused packages in Linux

Tired of running of low disk space? You may need to check for unused packages, in other term orphaned packages , filled in your hard drive. Orphaned (unused) packages are nothing but the packages which will be installed as a dependencies/libraries when you install a software in your linux box. As you know already, whenever we install an application, some other packages (dependencies) will also be installed along with the original application. These dependencies might exist in your hard drive even though you removed the application. After a particular period of time, your hard drive will be flooded with unused or orphaned packages, and you might end up with low disk space. Low disk space not only affects the system performance, it will also not let you to install new applications due to low disk space. So, it is very recommended to wipe out the orphaned packages in regular interval.

This brief tutorial will explain you how to remove unused, or unwanted, or orphaned packages in popular Linux distributions such as CentOS and Ubuntu. First, we will see how to find and remove unused packages in Ubuntu and its derivatives such as Linux Mint, elementary OS.

Find and remove unused packages in Ubuntu using Deborphan

Deborphanis a command-line utility that can be used to find and remove unused or orphaned packages in DEB based systems. It is available in the official repositories. To install it, open up the Terminal and run the following command:

sudo apt-get install deborphan

Once installed, run it as shown below to find out the orphaned packages.

deborphan

This will list all the unused packages.

openoffice.org-hyphenation
rhythmbox-plugin-magnatune
myspell-en-gb
libgnutls-openssl27
myspell-en-za
libusb-0.1-4
libreadline6

As you see above, I have few unused packages in my Ubuntu system.

To remove the orphaned packages, run:

sudo orphaner

Select the files and select Ok to remove the all fines.

Find and remove unused packages in Ubuntu using Gtkorphan

Gtkorphanis the graphical tool that allows us to find and remove orphaned packages. Gtkorphan is only for desktop editions. If you’re using Ubuntu server without GUI, use Deborphan instead.

Gtkorphan is available in the default repositories. To install it, run:

sudo apt-get install gtkorphan

Once installed, launch it by running the following command from the Terminal:

sudo gtkorphan

Gtkorphan’s default interface will look like below.

Since we already removed the orphaned packages, it shows nothing. However, at the first time, we need to initialize the system in order to keep track of needed packages, even if they are listed as orphaned.

To do so, from the main window, expand the“Options” section and check the box that says “Show all orphan packages, not only those in the libs section” .

Now, Gtkorphan will list the orphaned packages. However, you must careful here. As you see in the above picture, Gtkorphan lists some important packages as unused. We mustn’t remove them. In order to keep the important packages, right click on the package name, and click Hibernate package option.

This will keep the packages from removal by Gtkorphan. You only need to do this at the first time. After that, you can remove the orphaned packages if any exists.

Once you hibernated all important packages, scroll down through the list of other packages. If you don’t need any package, just rght click on it and click “Select for removal” option.

Alternatively, run the following command to remove the unused/orphaned packages all at once.

sudo apt-get autoclean && sudo apt-get autoremove

Congratulations! Now, you have free up some space in your hard drive.
