Proposal : in your “Code” boxes, separate prompt line from the body to ease copy/paste in one click
at step Debian: Getting Started with the BeagleBone Black , it not a tar.gz but a tar.zst
same thing here
Bash should see the # and only echo the first line, so you can copy paste the whole block.
Crap, this is a recent change, didn’t think of all the old script ramifications!
