Thanks for your help. I’m still learning Linux. Re: Packages, comming from decades of MS Windows experience, where so much is an automatic process handled by the OS, I assumed that the package database was automatically updated by Manjaro — didn’t know I needed to do it.
Re: Mirrors, I knew nothing about mirrors, or that such a database existed, which I think you guessed by the link you supplied me. Studying that page and the general Pacman info page, I learned all I needed to do the updates and retreive a new LTS kernel. My problem is now solved. Without your comments, I wouldn’t have been aware of what I needed to know. Thanks again!
