system crashed during update, pacman errors from chroot system resque

hi all,

so once again the system has crashed during pacman -Syu, rendering the system unusable. I've booted with the arch usb disk, chrooted to the damaged system, and tried to reinstall all corrupted packages
however

Packages (1) qt6-wayland-6.7.2-1

Total Installed Size:  7.07 MiB
Net Upgrade Size:      0.00 MiB

pacman fails to do anything. so the system remains in a corrupted state.
i tried to disable graphical target and boot into multi-user cli mode, but that fails as well.

thx

Re: system crashed during update, pacman errors from chroot system resque

Don't chroot - use "pacman --root=/mnt --cachedir=/mnt/var/cache/pacman/pkg …"
Don't forget to mount the boot partition into /mnt/boot, if you have one.
To see all deviating packages run

LC_ALL=C pacman --root=/mnt -Qkk | grep -v ', 0 altered files' | grep -v 'backup file:'
