Below is the error message I am getting with multiple packages. I am fairly new to Manjaro but have been studying it heavily here recently but cannot figure this out. My system shows that I currently have 820 available updates. I have updated the mirrors and repositories and nothing has fixed the issue. Any help would be greatly appreciated!
error: systemd-libs: signature from “Mark Wagie firstname.lastname@example.org” is unknown trust
:: File /var/cache/pacman/pkg/systemd-libs-251.2-3-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
