Looking for some help with HACS install - tried all i know

Hi - reached the end of my knowledge and looking for some help overcoming a problem in installing HACS on my new install of HA. Im running a Beeline S12 N100 NUC, with HA OS loaded directly. I have GitHub service loaded and logged into my GitHub acct. When i try to load HACS, I go to terminal, wget -O - https://get.hacs.xyz | bash - this connects to GitHub starts saving ‘hacs.zip’ and when it get to around 70-76% i get a ‘get : connection closed prematurely’. I have gone in removed the hacs.zip it puts in config/custom_components and re tried restarting HA, re trying a number of times etc with the same result. I then went to Github and downloaded the zip manually and created the HACS folder and copied the files from GitHub manual into it, and I could see the integration but it also failed - not sure where to go next, any pointers on what I’m dodging wrong appreciated

Have you tried this?

Also, NUC is a trademark of the Intel Corp. Beelink is not a NUC.
