If that doesn’t work, right-click the file and choose Open with software install. If you run into trouble with dependencies when using this method, try using Gdebi instead.
Having trouble finding your installed package? Just press the Super key (also known as the Windows key) on your keyboard, search for the application name, and then click it in the search results.

If you have Linux Mint, GDebi is already set up as your default package manager. If you’re using Ubuntu or Debian, you’ll need to install Gdebi. On Ubuntu, you can get Gdebi from Ubuntu Software. On Debian (or if you prefer Apt in Ubuntu), use these steps: Press Ctrl + Alt + T to open a terminal window. Type sudo apt update and press Enter. Enter your password when prompted. Type sudo apt install gdebi and press Enter or Return.
If you’re using Linux Mint, you can install the DEB file now through Gdebi by double-clicking it in your file manager and selecting Install Package. If you’re using Ubuntu or Debian and want to use the Gdebi GUI, open your file manager, right-click the DEB file, and select Open with Other Application. Choose Gdebi when prompted, and then click Install Package to complete the installation.

If you want to make Gdebi the default install tool for DEB packages in Ubuntu or any Ubuntu-related distribution, it’s easy: Right-click a . DEB file and choose Properties. Click the “Open with” drop-down menu and choose Gdebi Package Installer. If you want to uninstall a package you installed with Gdebi, use the apt command. The syntax is sudo apt remove packagename.
Apt is normally used to download and install software from remote sources, but you can use it to install local DEB packages using a special syntax. Unlike when using Gdebi to install DEB files locally, Apt will not automatically resolve dependencies. However, Apt does resolve dependencies automatically if you use it to install software from remote repositories.

Be sure to replace filename. deb with the actual name of the file, take note of the . / before it—if you leave it out, the apt tool will try searching for the package in remote repositories. If it’s the first time you’ve run a command using sudo in this window, you’ll have to enter your password when prompted to continue. To see a list of all installed packages with Apt, use the command sudo apt list –installed. To remove a package with Apt, use the command sudo apt remove packagename.
Dpkg comes preinstalled on all Debian-based Linux systems, including Ubuntu and Linux Mint. If you have trouble with dependencies using Dpkg, give Gdebi a try instead.

Make sure you enter the -i using a lowercase i, as Dpkg commands are case-sensitive. If it’s the first time you’ve run a command using sudo in this window, you’ll have to enter your password when prompted to continue.
To see a list of all installed packages with Dpkg, use the command sudo dpkg-query -l . You can easily remove packages with Dpkg using dpkg -r packagename. [3] X Research source
