Cannot satisfy dependencies for a system update

Further to what @anon59284200 said. ALWAYS check the forum post about updating the Manjaro system you are using. This is from the ‘stable’ branch.

  • You might be blocked updating when using pacman due to some libcanberra packages. Simply remove those packages: sudo pacman -Rdd lib32-libcanberra-pulse lib32-libcanberra-gstreamer libcanberra-pulse libcanberra-gstreamer. We recommend to use pamac anyway, which does this automatically: pamac update

Look under “Known issues and solutions”.

Like I said ALWAYS check the forum post about updates. That will keep you out of trouble.
