I'm not completely sure this is your problem, but the first thing that jumps out at me is # mount /dev/mapper/arch_root-image /mnt I'm pretty sure /dev/mapper/arch_root-image is the live system image, not your root partition. It looks to me like you need /dev/sda2 or /dev/sda3 as root (mounted at /mnt) and the other mounted at /mnt/home or /mnt/boot. The fdisk -l output doesn't tell which partition is for which mount point (except that sda1 is a swap partition), so you'll need to figure out which goes where. You could try mounting them all and looking at their contents: # mkdir -p /mnt/sda2 # mkdir -p /mnt/sda3 # mount /dev/sda2 /mnt/sda2 # mount /dev/sda3 /mnt/sda3 # ls /mnt/sda2 # ls /mnt/sda3 That should give you a hint on where to mount each partition. Then see what you need to do from there. I hope that helps a bit. :) On Mon, Mar 10, 2014 at 12:51 PM, Cao, Renzhi (MU-Student) <rcrg4@xxxxxxxxxxxxxxxxx> wrote: > Hi, all: > > I really have no idea for the pacman upgrading fails issue, so I summarize the problem I meet, and the things I try, if any one can give me suggestions of what I miss something or I do something wrong, I really appreciate, if not, I hope this summation can benefit some other people who meets the same problem. > > > The initial problem: > > After using pacman -Syu --ignore filesystem to upgrade my arch linux, and reboot, get the following message: > > ERROR: device '/dev/disk/by-uuid/3f51b ...' not found.
