All utilities, programs and other libraries in operating systems based on Linux are stored in packages. You are downloading a directory from the Internet in one of the available formats, and then add in local storage. Sometimes you may want to view a list of all present programs and components. The task is carried out by different methods, each of which will be most suitable for different users. Next, we will analyze each variant, taking the example of Ubuntu.
Viewing list of installed packages in Ubuntu
In Ubuntu there is and graphical interface, implemented by default in the Gnome shell, and there is the usual “Terminal”through which control of the entire system. Two of these components, you can view the list of added components. Choice of optimal method depends on the user.
Method 1: Terminal
First attention I would like to draw it to the console, because present in it standard tools allow you to use the full functionality to the maximum. As for displaying a list of all the objects is easy enough:
dpkgwith the argument
-lto display all packages.
dpkg-l | grep java, where java is the name required to locate the package.
dpkg-L apache2to get information about all the files installed via this package (apache2 — package name to search for).
dpkg -S /etc/host.confwhere /etc/host.conf — file itself.
Unfortunately, not everyone can use the console, and it’s not always necessary. That is why you should give an alternative display option list present in the package system.
Method 2: Graphical interface
Of course, the GUI in Ubuntu does not allow to fully carry out the same operations that are available in the console, but the visualization of the buttons and tools greatly simplifies the task especially for inexperienced users. First advise to contact the menu. There are several tabs, and sorting to display all programs or only popular. Search the package can be made via the corresponding line.
“Application Manager” will allow more detailed study of the question. In addition, this tool is installed by default and provides enough functionality. If for some reason the”application Manager” is missing in your Ubuntu, check out our other articles by clicking on the following link, and we go to search packages.

As you can see, working in “app Manager” is quite simple, but the functionality of this tool is still limited, so come to the aid of more advanced option.
Synaptic package Manager
Extra Synaptic package Manager will allow you to obtain detailed information about all added programs and components. First, still have to use the console:
sudo apt-get synapticto install Synaptic from the official repository.
Neither one of these methods you will not be able to locate the package during installation, which caused some errors, so watch out for the appearing notifications and pop-up Windows while unpacking. If all attempts ended in failure, then the required package is not present in the system or has a different name. Verify the name that is listed on the official website and try to reinstall the program.
