I'm not the most computer literate person and I have no problem with Linux, as a desktop. I don't know much Bash, because I don't need to. If I get stuck, I can normally find a solution by Googling it.
I wonder if anyone nearby could help him? If it's for work purposes, then it's within the COVID-19 rules. He could just pay a nominal amount, to tick the COVID box, just so no one gets fined.
