TrialnError  filed a deletion request for prosody-mod-carbons :
To quote the README for this module: 0.8 Works 0.9 Works 0.10 Included with prosody trunk Included with prosody
Since 0.10 this is included in prosody and as there is no prosody package for older versions on the aurweb I suggest to remove this PKGBUILD.
Best regards ___________  https://hg.prosody.im/prosody- modules/file/tip/mod_carbons/README.markdown#l47
