KDE Plasma 6.6.4 KVM Guest install completes with no issues. At the same time when I attempt straight forward setup Cosmic 1.0.10/11 ( making choice in installation setup menu ) Calamares installer constantly crashes. If I try in KDE Plasma to run $ pacman -S cosmic cosmic-session dependencies conflict comes up forcing me to erase one package ( kind of mesa-git not sure about exact name ) .
Cosmic installs and doesn’t show any visible issues as well as re-login to KDE Plasma still behaves smoothly at first glance of-course. Issue has been reproduced when deploying KVM VMs via the most recent cachyos-desktop-linux-260426.iso
