@acolaja ,
First, if you have Linux Lite 4.2 64bit installed, you would use the amd debian files. AMD and x64 pretty much mean 64-bit architecture. i386 pretty much means 32-bit architecture, and Linux Lite 4.2 does not come in a 32-bit flavor. So since you have 64-bit Linux Lite 4.2 installed on 64 bit architecture, use the AMD files.
Secondly on the *.deb files, you could run them one at a time by double clicking on them and they will install via Gdebi. Or from the folder where the amd deb files are located, open a terminal, and use the following command. This command will install both debian files in one shot. Make sure just the AMD debian files are in the folder or else it could attempt to install the i386 debian files, too:
sudo dpkg -i *.deb
The command is taken from this link:
