After upgrading the system with yay

:: Searching AUR for updates…
→ kvantum-theme-matchama: local (20191118-1) is newer than AUR (r265.8525e05-2)
→ Missing AUR Packages: linux513 yaourt

Why do these messages appear?

linux 513 is eol, so remove it
and the package that is newer can be ignored, or you can downgrade it if it causes issues

Thanks

yaourt has finally be removed

A message appeared while uninstalling linux513. This is fine?

sudo yay -R linux513

Not quite. One should always use Manjaro Settings Manager or MHWD to install or remove kernels; i.e.,

sudo mhwd-kernel -r linux513
