ca-certificates-utils: /etc/ssl/certs/ca-certificates.crt exists in filesystem
Errors occurred, no packages were upgraded.


Solution:

remove /etc/ssl/certs/ca-certificates.crt e.g.:

$ mv /etc/ssl/certs/ca-certificates.crt/etc/ssl/certs/ca-certificates.bak


Good advice:

update keyrings before the full update:

$ pacman -S archlinux-keyring
