MarsSeed [1] filed a deletion request for adapta-kde-git [2]: Defunct VCS package for a KDE5 Kvantum-Qt5 theme discontinued since 2018. [a] GitHub repo archived since 2020.
Even on KDE5, there were some issues (graphic glitches) when I tried this out in 2021 on KDE Plasma. [a]: https://github.com/PapirusDevelopmentTeam/adapta-kde [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/adapta-kde-git/
