Thanks for all the suggestions. I have one further question.

When I first set up an Electrum wallet, I see that I went through Kleopatra, GPA, etc., as I still have these on my old laptop screen.

The thing is that I cannot remember the whole process, especially because I am not tech-savvy.

Is it enough for me just to download the latest Electrum software to my new PV and verify the signature?

This requires Kleopatra, if I recall, correct? Is there any link to a step by step process?
