It’s almost like the good ol’ days of install fests and the like! ‘End of 10’ is an organization that’s making it easy for Windows 10 users with computers that can’t upgrade to Windows 11, to install Linux instead of sending good hardware to the landfill.
endof10.org seems like a good website to direct people to via posters in your local community center or church. Or you can call a repair club in your area to ask if they want to be listed. Those are likely to have some Linux enthousiast members and already have a location.
