The Complete Guide to the Synaptic Package Manager

Use a more complete graphical package manager on Ubuntu

An alternative to the Ubuntu Software Center is the Synaptic Package Manager. The Synaptic Package Manager has benefits over the Ubuntu Software Center, such as no advertisements for paid-for software and results display from all the repositories in your sources.list. Synaptic is also a common tool used by other Debian-based Linux distributions. So, if you switch distributions, you can use this familiar tool to install applications.

How to Install Synaptic

On Ubuntu, use the Software Center to search for and install Synaptic. Alternatively, if you prefer to use the command line or you use another Debian based distribution, open a terminal window and type the following:

sudo apt install synaptic

The User Interface

The user interface has a menu at the top with a toolbar underneath. There's a list of categories in the left pane. The right pane lists applications in that category.

As well as a description of the application, there are buttons and links for Screenshot, Changelog, and Visit Homepage.


If you click an application and then click the Properties button, a new window appears with these tabs: Common, Dependencies, Installed Files, Versions, and Description.

The Dependencies tab lists the other applications that need to be installed for the selected package to work.

The Installed Files tab shows the files that are installed as part of a package.

The Versions tab shows the available versions of the package.

The Description tab shows the same information as the Application Description panel.


The Search on the toolbar displays a window with a box where you enter a keyword to search for and a drop-down list to filter what you are searching on.

The drop-down list contains the following options:

  • Name
  • Description and name
  • Maintainer
  • Version
  • Dependencies
  • Provided Packages

Generally, you search by description and name, which is the default option. 

If, after searching, the results list is too long, use the quick filter option to filter the search results further.

The Menu

The menu has five top-level options: File, Edit, Package, Settings, and Help.

The File Menu

The File menu has options for saving marked changes in the file system. This is useful if you have marked a number of packages for installation, but you don't have the time to install them at the moment. So that you don't lose the selections and have to re-select them later, click File > Save Markings As, then enter a filename.

To read the file back in later, select File > Read Markings. Choose the saved file and open it.

There is a generate package download script option available on the File menu. This saves your marked applications in a script that you can run from the terminal without having to reload Synaptic.

The Edit Menu

The Edit menu has similar options to the toolbar, such as reload, apply, and mark all applications for upgrade. The best option is to fix broken packages, which attempts to do exactly that.

The Package Menu

The Package menu has options that mark applications for installation, reinstall apps, upgrade apps, and remove and completely remove apps. You can also lock an application at a particular version to prevent it from upgrading. This is useful if you need certain features that have been removed from newer versions or if you know the newer version has a bug.

The Setting Menu

The Settings menu has an option called Repositories. This option displays the Software and Updates screen where you can choose to add extra repositories.

The Help Menu

The Help menu has a comprehensive help guide where you can learn more about the Synaptic Package Manager.
