This is my first time messing with Linux so please forgive my ignorance.

I have an HP Elitebook 840 G8 that I’ve installed Ubuntu server on. I was trying to install a GUI on it, so I tried pulling the SLiM package from the web, but got "Temporary Failure resolving ‘Archive.ubuntu.com’.

This laptop doesn’t have an Ethernet Port, so I have to use a Microsoft USB-Ethernet dongle. But I haven’t been successful in getting that to work.

Is there a way for me to manually download the driver on a USB, then load it that way?
