How to Install Software on Debian Bookworm Command Line

Installing Downloaded Packages

1. 1. Installing Downloaded Deb Packages

   Now to Install Downloaded Deb Packages on Debian
   First, access the Download location by default with:

   cd ~/Downloads

   To Check it’s there List the contents with:

   ls . | grep [MYPACKAGEKEY]

   The grep Command refine the output List showing only the Entries matching the Keyword.
   But if you are in Trouble to Find it out on Terminal then See: How to Access Downloads Folder from Browser.
   Then you have 2 possible Solutions.

   In case of a Package without external Dependencies you can go with:

   sudo dpkg -i ./[MYPACKAGE].deb

   Hence for a Google-Chrome Web Browser Setup:

   sudo dpkg -i ./google-chrome*.deb

   Super-Tip: use “*” to Short the Command or the Tab Key to Autocomplete!

   Especially relevant: at first glance you are usually Unable to know if the Software is Self-dependent.
   Thus it’s always suitable to use instead apt Package Manager or gdebi Package Installer to handle the possible Dependencies.
   Now to Install the Software using apt:

   sudo apt install ./[MYPACKAGE].deb

   Like:

   sudo apt install ./google-chrome*.deb

   

   Last, as a valid Alternative you can Install and use gdebi:

   sudo apt install gdebi

   And then:

   sudo gdebi ./[MYPACKAGE].deb
