Hi: while package upgrades are usually very smooth, there are scenarios where a symlink to a shared object (.so) file or an outdated file (eg. .pyc) is left on the file system.
As a result during the upgrade one sees error notifications for untracked files. The "--overwrite" is helpful when using 'pacman'. Please see two examples here zn_poly update https://www.archlinux.org/news/zn_poly-092-2-update-requires-manual-intervention/ firewalld update https://www.archlinux.org/news/firewalld081-2-update-requires-manual-intervention/ warm regards Saifi.
