This method can be utilized to add a key to the pacman keyring, or to enable signed unofficial user repositories. Each repository section allows defining the list of its mirrors directly or in a dedicated external file through the Include directive; for example, the mirrors for the official repositories are included from /etc/pacman.d/mirrorlist. See the Mirrors article for mirror configuration. error: pipewire-common-pulse-git: signature from "Pedro Henrique Lara Campos " is unknown trust This is happening because pacman has detected a file conflict, and by design, will not overwrite files for you.

If even pacman-static does not work, it is possible to recover using an external pacman. One of the easiest methods to do so is by using the archiso and simply using --sysroot or --root to specify the mount point. See Chroot#Using chroot on how to mount the necessary filesystems required by --sysroot.
