   Fist, make the Target Directory:

   mkdir ~/Downloads/linux

   Then Copy the downloaded Stuff into the Folder by the File Manager or on CLI with:

   But if you are in Trouble to Find it out on Terminal then See: How to Access USB Device.
   Then access the Target:

   cd ~/Downloads/linux

   ls . | grep linux

   The grep Command Refine the output List showing only the entries Matching the Keyword.
   And then to Setup New Linux Kernel play:

   sudo dpkg -i ./linux*.deb

   Finally, Reboot to load it:

   sudo reboot

   aptitude search '~i!~M' | grep linux

   In the Output you’ll find Trace of the Package Names.

   Next the Deleting Command is resumed in:

   sudo apt purge [MYPACK1] [MYPACK2] [MYPACK3] [MYPACK4]

   Again the Right-Click or Ctrl+Shift+v to Paste in the Identifiers.
