MarsSeed [1] filed a deletion request for kdebase-runtime [2]: Quote from comment: alexz commented on 2021-07-17 04:30 "kdebase-runtime is no longer needed. Looks unmaintained too." Source linked is 4.5 years old. There is no kde-runtime component anymore in KDE. Build has been reported to fail for the last couple of years. This library seems incompatible with newer base libraries of KDE or with ICU. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/kdebase-runtime/
