Kernel panic after uninstall amd-ucode

[holon]

Hello, I have uninstalled amd-ucode and have a kernel panic, then I tried to fix this way:

1. Use Manjaro Live USB to get a terminal
2. Then, this commands:

sudo -i
mount -t ext4 /dev/sda4 /mnt/
mount -t ext4 /dev/sda4 /mnt/home
mount -t ext4 /dev/sda4 /mnt/var/log
mount -t ext4 /dev/sda4 /mnt/var/cache
mount -t vfat  /dev/sda1 /mnt/boot/efi
mount --bind /dev /mnt/dev
mount -t proc proc /mnt/proc
mount -t sysfs sysfs /mnt/sys
mount -t efivarfs efivarfs /mnt/sys/firmware/efi/efivars
chroot /mnt /bin/bash

But when I tried:

pacman -Syu amd-ucode

Failed to synchronize to all databases, and when:

pacman-mirrors -f && sudo pacman -Syyu

shows me the error that, Internet connection appears to be down, but it is up and working.

Then I tried to download the package and install it locally but:

pacman -U /home/manjaro/Downloads/amd-ucode-20260110-1-any.pkg.tar.zst

loading packages…

error: ‘/home/manjaro/Downloads/amd-ucode-20260110-1-any.pkg.tar.zst’: could not find
or read package

Now, I don’t know how to fix the problem.

First boot a rescue ISO or a live ISO - follow the guide to mount and chroot

Then install the package

pacman -Syu amd-ucode
