@JPL, you may want to check via pacman -Qi mutter46 why you might have installed this package. Normally it is a dependency of these packages: gala, lightdm-pantheon-greeter, wingpanel
@rousseau: libva-vdpau-driver got removed from the repos and is therefore orphan. It is save to remove it. libva is now provided by mesa.
@Kyoketsu9513 networkmanager-pptp 1.2.12-4 and networkmanager-l2tp 1.20.16-2 are fine with ppp 2.5.1. So your mirrorlist might not been updated. Check that and try again.
@Humbi your issue sounds like this one: [SOLVED]Nvidia Persistence Daemon fails to start / Newbie Corner / Arch Linux Forums. This update normally removes linux610 kernel. You can check first if you have all modules of nvidia drivers installed for the newer kernel. You also can install an older kernel like 6.6. You can check with pacman -Q | grep nvidia on what is installed Nvidia related on your system.
