The error:
pipewire-libcamera : Depends: pipewire (= 1.0.3-2~ubuntu22.04) but 1.0.2~1707732619~22.04~b8b871b is to be installed E: Unable to correct problems, you have held broken packages.I tried adding the pipewire testing PPA which contains the indicated version 1.0.3-2~ubuntu22.04 fromsudo add-apt-repository ppa:pipewire-debian/testing but it won't install manually.
Then I saw the upstream PPA already contains the version yet it won't install manually.
