USe this work-around, until the Antergos build guy gets back from holidays/vaction, and fixes the build server and a new version of liblastfm-qt5 is published
As pointed out liblastfm-qt5 is the cuplrit (dependency for Clementine -> antergos-kde-meta), this time we will remove the clementine dependency from antergos-kde-meta.
We do this by updating package.xml and replacing antergos-kde-meta with the dependencies (with clementine removed).
run cnchi specifying the package.xml file - and it works!!!
NOTE: to speed things up (if you’ve done multiple install attempts), I recommend copying the pkg cache to a USB or virtual drive, and let cnchi know you have a cache, this means you don’t have to download all packages again
