Authentication failed in 2026

This is a known issue with the latest polkit.

You will need to use Linux 6.6 or better.

Anything older will not support certain kernel function calls.

I am suggesting you run the most recent kernel

sudo mhwd-kernel linux618 rmc

These are custom packages from AUR.

Run

sudo pacman -Syu

Then you can continue to rebuild your custom packages.

[Stable Update] 2026-01-13 - Kernels, KDE Gear 25.12.1, Haskell, Mesa

Prepare the update beforehand

Preparation steps

From [INFO] Stable branch - BIG update BEST practice

If it has been a long time since your last update, you may want to refresh your pacman-keyring before running the actual update.

Create a list of custom packages for later reference
pamac list --foreign > ~/alien-pkgs.txt
Remove all foreign packages
pamac remove $(pamac list --foreign --quiet)
Remove all orphans and other unneeded packages
pamac remove --orphans --unneeded
Optional: ensure the keyrings are up-to-date
sudo pacman -Syy manjaro-keyring archlinux-keyring
Optional: Run a simulated update
pamac update --dry-run
Looking good? Repeat the above without --dry-run
reboot
Consult the list of packages created in the first step and rebuild only those you really need

Important Note: Users of Plasma and GNOME may lose their X11 session support. Checkout our guides below before restarting your systems!

Important Note: Users of Pascal, Maxwell, or older cards will fail to load the NVIDIA driver when they were using 580xx series earlier, because the 590xx doesn’t support the older hardware anymore. Only Turing series and newer are still supported.
