This is a silly question but can you install software from debian packages without having an internet connection ?

Yes, it is possible. One of the methods is to use the command:

sudo dpkg -i filename.deb

You can also try to install the file via Ubuntu Software/Snap Store application by double clicking on it in file manager (although this usually didn't work for me - but in theory it's supposed to work).

One more method is to use GDebi, it's a GUI installer for .deb files. It is my preferred tool to install non-repository packages. But it's not installed by default, so you have to install it first while you do have an Internet connection.

However, if the package to be installed has any dependencies, you must resolve them manually and install all dependencies first.

Yes, you can do it by using Gdebi. Suppose, you have already downloaded a Deb package software-package-example.deb. To install it, open terminal in the same directory where the package is downloaded and type

sudo gdebi software-package-example.deb

Done.

If Gdebi is not installed, you can run

sudo apt-get install gdebi

    And to run sudo apt-get install gdebi you need internet which defeats the purpose of the question. The other answer using dpkg is the correct one. No additional software is required. – ChanganAuto May 17 '21 at 15:58
