Check How to install deb file in Ubuntu
My main browser is Google Chrome (hey, I like it, let me be). Every time I install Ubuntu or a derivative like Pop! I usually have to go out of my way to download _OS or Linux Mint from an approved source. It’s already easy to install Google Chrome on Ubuntu: go to the Chrome website, download the latest installer.deb, and then sudo dpkg -i install it (although you could just double-click deb and install it using a GUI, like a Joe, but hey .
Introduction to the Deb file in Ubuntu
Some programs exist in deb packages. These packages are the archived files that end with the extension ie .deb. We can assume a .deb file as an .exe file within Windows. When we double click on the .exe file, it will start the installation process in Windows. In Ubuntu, the deb packages are quite similar. Troubleshooting: Double click deb file not opening within Software Center in Ubuntu version 20.04. It’s weird, but could be easily solved. We have to right click on that deb file and select the option ie “Open with”. We can select to open with the Software Installation option as the default selection.
Download the deb file
We are downloading and installing the TeamViewer deb file for demo purposes. TeamViewer can be defined as an all-in-one key for file transfer between computers, online meetings, desktop sharing and remote support. Start our web browser and connect to TeamViewer for Linux download page. We can download the deb package by clicking on the Debian and Ubuntu download link. If we prefer the command line, we can download our deb file using curl or wget.
$ wget –no-check-certificate https://download.teamviewer.com/download/linux/teamviewer_amd64.deb
EITHER,
$ curl -k -O -L https://download.teamviewer.com/download/linux/teamviewer_amd64.deb
Install the deb file using the command line
If we want to install the deb packages using the command line, we have several tools at our disposal. We will show how to apply the dpkg, gdebi and apt utilities to install deb packages.
Install the deb file using the apt utility
apt can be defined as a command line utility to install, update, remove and manage various deb packages on Ubuntu, Debian and other related Linux distributions. The apt utility was announced in Ubuntu version 14.04 and includes the most commonly used commands via apt-cache and apt-get.
To install local deb packages using apt, we need to give the full path to the deb file. When the file is placed in our current working directory, instead of providing the absolute path, we can prepend ./ before the package name. Otherwise, the apt utility will try to install and retrieve the package through the Ubuntu repositories.
$ sudo apt install ./teamviewer_amd64.deb
We will be prompted to type Y to continue. After that, apt package manager will repair and install all package dependencies.
Install deb files using gdebi
gdebi can be described as a tool for installing local deb packages. By default it is not installed on Ubuntu, however we can install these packages using the following command:
$ sudo apt install gdebi
To install the deb packages using gdebi, we need to type:
$ sudo gdebi teamviewer_amd64.deb
When prompted, type y and gdebi will repair and install the deb files and all dependencies for us.
Install deb files using dpkg
dpkg can be defined as a (low-level) package manager for all Debian-based systems. We can apply the -i or the -install option to install deb packages using dpkg.
$ sudo apt install./teamviewer_amd64.deb
dpkg does not resolve dependencies, unlike gdebi and apt. If we encounter any dependency errors during deb package installation, we can apply the following apt command to resolve and install each package dependency:
$ sudo apt install -f
Install deb packages with GUI
- We can simply download the deb file and start it with a double click if we prefer to apply the graphical interface.
- A default distribution graphical software center will open:
- Press the install button and a dialog will open i.e. Authenticate:
- We have to type the administrative password and click on the Authenticate button.
gui mode
If we want to apply GUI GDebi, we can follow the next steps:
- Open the file manager and drop the package. We can see it in Downloads in most cases.
- Right click on the deb files and select “Open with another application”
After doing the above step, a new dialog will open along with the Recommended Applications group. Select the GDebi package installer and press Select. This installer will load all deb packages and display the software description (if any) and whether each dependency is satisfied. Press the Installation Package, enter the password and press the Authentication button to start the installation process. The installation process may take some time depending on the size of the file and its other dependencies. The button ie “Install” within the Ubuntu Software Center will change to “Remove” when the deb file is installed. That’s it, our application has been successfully installed on our system and we can start using it.
Deleting deb files
Consider the following methods to remove deb files.
Uninstall the deb file with the Software Center
We can remove the package by opening the terminal window even if we have successfully installed the package with Software Center and running the following command:
sudo apt remove [software_name]
Software removal by dpkg
We can use the official package name dpkg in the following command when removing packages installed by it:
sudo dpkg -r [software_name]
Software removal by Gdebi
To uninstall the Gdebi software, we have to open the Gdebi Package Installer and click on Remove Package
