"How To Install and Remove Deb Packages On Ubuntu - Step-by-Step Guide"
30In this video I cover how to install and remove deb packages in Ubuntu 23.10 or newer.
One of the major changes that was made in Ubuntu 23.10, was the replacement of the Ubuntu Software application with the App Centre, which I have found has two regressions in functionality.
Firstly, you cannot use the App Centre to install any deb packages you may have downloaded, and second, you also cannot use the App Centre to remove any installed Debian packages, only install.
Therefore the solution is to use the Gnome Software application to restore this functionality.
Step 1. Install Gnome Software.
To install Gnome Software, open the App Centre, search for "Software" and select the result that appears under the Debian packages section.
From here, click on the green Install button, and once installation has finished, launch for the first time.
Step 2. Install Deb Files With Gnome Software.
Now that Gnome Software is installed, we can use it to install any deb packages we have downloaded, however to make this default, we need to make a quick change.
Right click on any downloaded deb file, select the Open With... option, and scroll down the list until you see a Software Install option.
Make sure to click this option, as well as the toggle for "Always use for this file type" at the bottom, and finally click Open to start the installation process.
In the future, this means that any deb files you double click on, will open automatically in Gnome Software, but in either case, click the Install button, and once the installation process has finished, launch the application as normal.
Step 3. Remove Debian Packages Using Gnome Software.
To remove any installed deb packages, open Gnome Software, click on the Installed tab which will give a list of all installed applications.
So to remove an application, click Uninstall.
Now for some reason, some applications installed using deb files will not appear on this list.
So to remove those applications, run the downloaded deb file again and you should get an option to uninstall rather than install.
