Tried to do a packer -Suy, and it returned a 404 after downloading the first package. Concerned, I ran packer -Suyy, and it only upgraded glib2. So I tried installing the packages that needed upgrading manually, and it gave a file conflict error. Since I only run my Raspberry Pi Zero headless, is it safe to run pacman with --force?
