Package `libspeechd` is both in world and galaxy repos; outdated `world/libspeechd 0.10.2-1`, current `galaxy/libspeechd 0.11.1-2`. After installing package `galaxy/speech-dispatcher 0.11.1-2` (optional dependency of firefox), `pacman -Suu` always fails because it tries to downgrade `libspeechd`:
# pacman -Suu
:: Starting full system upgrade...
warning: libspeechd: downgrading from version 0.11.1-2 to version 0.10.2-1
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: installing libspeechd (0.10.2-1) breaks dependency 'libspeechd=0.11.1-2' required by speech-dispatcher
I suggest removing `libspeechd` from `world` because `speech-dispatcher` is in `galaxy` only.
Should be fixed now. Thanks for reporting.
Thank you. :)
