Hi, Tom . . .
Thank you very much for your prompt reply. I am pretty comfortable using the command line. I do have to occasionally Google commands but the from the search results I can usually figure out the proper syntax for the Linux command I need to run.
Here is the error message when I ran the command from Step 1:
Reading package lists. . . Done
N: Skipping acquire of configured file ‘main/binary-arm64/Packages’ as repository "https://repo.windscribe.com/debian stretch InRelease’ doesn’t support architecure ‘arm64’
Tom, this message may be due to the fact that I am using putty from a Windows 10 Pro computer to communicate with my Vero 4k via the command line.
