Uninstall Using Synaptic Package Manager

  1. Image titled Uninstall Ubuntu Software Step 1
    Open the Package Manager. Ubuntu comes installed with a GUI (Graphical User Interface) package manager that lets you remove programs within a visual window. This is useful if you aren’t comfortable with command lines.

    • Click on System, then select Administration. From the Administration menu, select Synaptic Package Manager.
    • Some of the more recent versions of Ubuntu do not come with Synaptic preinstalled. To install it, open the terminal and type:sudo apt-get install synaptic
    • If you are using Unity, open the dashboard and search for “Synaptic”

    Browse for the program that you want to uninstall. In the left frame, you can sort the listed programs by category. The installed programs (packages) will be listed in the upper frame of Synaptic.

    • Oftentimes programs are referred to by their abbreviated names. For example, Media Player would be called “mplayer”. If you are unsure of the shortened name of the program you want to remove, search for it online before trying to delete it.
