How to install Deb files in Ubuntu, for this problem, this article describes in detail the corresponding analysis and answers, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Install .deb files in Ubuntu and Debian-based Linux distributions

You can choose a GUI tool or a command line tool to install a deb package. You have a choice.

Let's move on to how to install the deb file.

Method 1: use the default Software Center

In Ubuntu, the easiest way is to use the default software center. You don't have to do anything special here. Just go to the folder of the .deb file you downloaded (it should be the Downloads folder) and double-click on the file.

Google Chrome's deb file on Ubuntu

Double-click on the downloaded .deb file to start the installation.

It will open the Software Center, and you will see the options for installing the software. All you need to do is click the install button and enter your login password.

Install Google Chrome in Ubuntu Software Center

The installation of .deb files will be performed through the Software Center.

Look, it's even easier than installing a .exe file in Windows, isn't it?

Method 2: use the Gdebi application to install the deb package and its dependencies

Again, life might be easier if things always went well. But life is not what we know.

Now that you know that .deb files can be installed simply through the software center, let me tell you some dependency errors that the package may encounter.

The reason for the error is that one program may depend on another package (library). When a developer prepares a DEB package for you, he or she may assume that your system already has a dependent package (library).

But if this is not the case, and your system does not have the required packages (libraries), you will encounter the infamous "dependency error".

The software center cannot handle such errors, so you have to use another tool called gdebi.

Gdebi is a lightweight GUI application that serves only one purpose of installing the deb package.

It will identify dependencies and try to install them while installing the .deb file.

Gdebi handles dependencies when installing the deb package

Personally, I prefer to use gdebi rather than the package Center to install deb files. It is a lightweight application, so the installation process looks a little faster. For more information, you can read about using gDebi and making it the default setting for installing DEB packages.

You can install gdebi from the Software Center or by using the following command:

Sudo apt install gdebi method 3: install the .deb file using dpkg on the command line

If you want to install the deb package on the command line, you can use the apt command or the dpkg command. In fact, the apt command uses the dpkg command at the bottom, but apt is more popular and easier to use.

If you want to use the apt command on the deb file, use it like this:

Sudo apt install path_to_deb_file

If you want to use the dpkg command on the deb package you are going to install, here is how to do it:

Sudo dpkg-I path_to_deb_file

In these two commands, you should replace path_to_deb_file with the path and name of the deb file you downloaded.

Use the dpkg command to install the deb file in Ubuntu

If you get a dependency error while installing the deb package, you can use the following command to fix the dependency problem:

How sudo apt install-f removes deb packages

Removing a deb package is not a big deal. Also, you don't need the original deb file used to install the program.

Method 1: use the apt command to remove the deb package

All you need is the name of the program you have installed, and then you can use apt or dpkg to remove the program.

Sudo apt remove program_name

Now, the question is, in the remove command, how do you find the exact program name you need to use? To do this, the apt command also has a solution.

You can use the apt command to find a list of all the installed files, but completing the process manually can be a headache. Therefore, you can use the grep command to search for your package.

For example, in the previous section, I installed the AppGrid application, but if I want to know the exact program name, I can use something like this:

Sudo apt list-- installed | grep grid

This will give me all the names of the software packages that contain "grid", from which I can get the exact program name.

Apt list-- installed | grep gridWARNING: apt does not have a stable CLI interface. Use with caution in scripts.appgrid/now 0.298 all [installed,local]

As you can see, a package named "appgrid" has been installed. Now, you can use this program name in the apt remove command.

Method 2: use the dpkg command to remove the deb package

You can use dpkg to find the name of the installed program:

Dpkg-l | grep grid

This output will be given to all packages with "grid" in their name.

Dpkg-l | grep grid ii appgrid 0.298 all Discover and install apps for Ubuntu

The ii in the above command output means that the package has been installed correctly.

Now that you have the program name, you can use the dpkg command to remove it:
