   Or from Command Line:

   cd /[path/2/device]

   tar xvzf *.tar.gz -C /tmp/

4. 4. Downloading Kernel Headers & Source

   So Download the Right kernel-devel & kernel-headers Packages
   First, find out the Kernel Version with:

   uname-r

   Take Note of the Digits prior to “fc31” to searching for the kernel-devel Package!

   Download kernel-devel/kernel-headers for Fedora 31 GNU/Linux

   Get kernel-devel+kernel-headers .rpm Packages

   First, see in the Actual Fedora 31 Repo.
   Or else try on fedora.pkgs.org.
   But in case you do not find an available version the first look: How to Install New Kernel offline.

   Then to Install Kernel Headers & Source Code
   First, extract the Archive as for the previouse Tools:

   cd /[path/2/device]

   sudo dpkg -ivh kernel*.rpm

6. 6. Installing Packages

   Then to Install Required Packages
   First, access the Target Packages Location:

   cd /tmp/packages

   To Check the Package are there:
