System upgrade failing due to conflicting dependencies

[Takakage]

Is that the only error message that you are getting? It sounds related to the chain of dependencies around kpeoplevcard. From the stable update announcement:

@philm

kpeoplevcard update requires manual intervention

A “newer” version of kpeoplevcard accidentally existed, so to install the current version, either update with sudo pacman -Syu kpeoplevcard or sudo pacman -Syuu.
