I can't upgrade my system

Welcome here, @mancardo,

Are you using a printer requiring the cuda package? If not, you probably could solve the issue as described in this post:

[Nvidia] Deprecation of 340xx driver series

NVidia 340xx: Problems with update 09/08/2020 and workaround Today’s upgrades wouldn’t work: the cuda package insisted on nvidia-450xx, and there were a number of conflicts. Workaround: I added IgnorePkg = cuda to /etc/pacman.conf , pinning the package to its current version. Thereafter things ran smoothly, but of course that package is now frozen in time. I’m not exactly happy about nvidia-340xx being deprecated, and I kind of do see more problems of this kind looming on the horizon.
