After updating using yay -Syu this lines showed up on the terminal:
-> Missing AUR Packages: mhwd-catalyst python-sip-pyqt5 xf86-input-keyboard xf86-input-mouse
-> Flagged Out Of Date AUR Packages: python-qdarkstyle
Now I can use neither desktop nor mouse. The packages are installed and even with sudo pacman -Syuu I cannot find a match.
Thanks in advance
