I want to install the latest updates of Ubuntu in my laptop, but while clicking on show updates... It is throwing a The package system is broken error, and it is asking me to disable the third party repositories.

I tried unchecked the third party repositories in the Other software tab in Software & Updates, but I am unable to disable them.

Now how to disable the third party repositories? Without disabling, it is not allowing me to install the latest updates.

I am facing the below error

=================================
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
 The following packages have unmet dependencies:

virtualbox-5.2:i386: Depends: libcurl3 (>= 7.16.2) but 7.47.0-1ubuntu2.9 is installed
 Depends: libdevmapper1.02.1 (>= 2:1.02.97) but 2:1.02.110-1ubuntu10 is installed
 Depends: libgcc1 (>= 1:4.2) but 1:6.0.1-0ubuntu1 is installed
 Depends: libice6 (>= 1:1.0.0) but 2:1.0.9-1 is installed
 Depends: libsdl1.2debian (>= 1.2.11) but it is not installed
 Depends: zlib1g (>= 1:1.1.4) but 1:1.2.8.dfsg-2ubuntu4.1 is installed

To workaround the problem (bug) of not being able to select/deselect repositories in Software & Updates, open Synaptic, enter your password, then select Repositories from the Settings menu.

But wait... do this first. In Synaptic, go to the Edit menu and select Fix Broken Packages. Do this twice. Then click the Reload icon, and if any errors appear, you need to fix those, to help solve your problem.

Once done, you probably won't need to disable repos, and you can continue with your Software Updater app.

Also, I'm guessing that you have a 64-bit computer, and virtualbox-5.2:i386 would be the wrong version of VB. You probably need to uninstall this version and install the 64-bit version. You can use Synaptic to do this.

After trying to uncheck the third party repositories in the Other software tab in Software & Updates a new small window opens up with a Reload button that refreshes the list of available software. The Reload button is marked by the mouse cursor in the below screenshot. Maybe you didn't click the Reload button, so your list of available software did not get updated, and as a result the package system is broken.

The information about available software is out-of-date 

To install software and updates from newly added or changed sources, 
you have to reload the information about available software.

You need a working internet connection to continue.

Run the following command in the terminal to refresh the list of available software.

sudo apt update 

After that you can download the VirtualBox .deb file for Ubuntu 16.04 from the official Oracle website and double-click the .deb file to install it, or follow the instructions for adding the Oracle VirtualBox repository to your software sources at the Oracle VM VirtualBox virtualbox.org webpage. Installing VirtualBox using the second option allows VirtualBox to be updated automatically, but this feature is not necessary because if you install VirtualBox using the first option you will be prompted in the VirtualBox application to update it to the latest version when an update is available.

  Replacing the sources.list file with a generic template will only LOSE some custom repos they've added. Most third party repos get added via the sources.list.d directory as *.list files.

The information about available software is out-of-date 

To install software and updates from newly added or changed sources, 
you have to reload the information about available software.

You need a working internet connection to continue.

Run the following command in the terminal to refresh the list of available software.

sudo apt update 

After that you can download the VirtualBox .deb file for Ubuntu 16.04 from the official Oracle website and double-click the .deb file to install it, or follow the instructions for adding the Oracle VirtualBox repository to your software sources at the Oracle VM VirtualBox virtualbox.org webpage. Installing VirtualBox using the second option allows VirtualBox to be updated automatically, but this feature is not necessary because if you install VirtualBox using the first option you will be prompted in the VirtualBox application to update it to the latest version when an update is available.

After trying to uncheck the third party repositories in the Other software tab in Software & Updates a new small window opens up with a Reload button that refreshes the list of available software. The Reload button is marked by the mouse cursor in the below screenshot. Maybe you didn't click the Reload button, so your list of available software did not get updated, and as a result the package system is broken.

  The OP can't uncheck third party repos in the Software & Updates app. See my answer.

  Same thing. OP can't uncheck/disable third party repos. It's an admin password bug.

  Replacing the sources.list file with a generic template will only LOSE some custom repos they've added. Most third party repos get added via the sources.list.d directory as *.list files.

  Oh no! Delete every file in sources.list.d?!? Not a good idea. Why take the sledgehammer approach when my answer solves the problem?
