Cant mount partition to sudo-chroot

General system Kernel, boot, graphics & hardware

Yesterday, I ran I think yay -Ssyu?? or pacman -Ssyu to update system packages. The terminal went blank after all the loading bars were finished only letting me enter to add more paragraph breaks and type without doing anything, so I closed the terminal thinking it was probably done. Rookie error, now I can’t boot.

Currently following this guide: https://discovery.endeavouros.com/system-rescue/arch-chroot/2022/12/ and I can’t seem to mount either of my partitions. Here is what my terminal looks like:

sudo lsblk -l
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
loop0 7:0 0 2.7G 1 loop /run/archiso/airootfs
sda 8:0 1 57.7G 0 disk
sda1 8:1 1 2.9G 0 part /run/archiso/bootmnt
sda2 8:2 1 248M 0 part
nvme0n1 259:0 0 931.5G 0 disk
nvme0n1p1 259:1 0 931.5G 0 part

sudo mount /dev/sda2 /mnt - no response, assumably works

sudo cat /mnt/etc/fstab
cat: /mnt/etc/fstab: No such file or directory

ls -l /mnt

you are trying to mount the wrong drive. you need to mount

Ah yeah, you’re right - totally rookie error now that I look at the file sizes :sweat_smile:

The next chroot instruction is to mount the ESP, but there’s only one partition under nvme0n1, so what would it be mounting to?

Here’s the instructions on the link:

So we need to mount /dev/sda2 and the ESP (/dev/sda1) make sure to know your ESP mount point on your installed system can be /efi or /boot/efi (older installs, or if you are using grub instead of systemd-boot).

You will see in the /etc/fstab file of the installed system if you cannot remember.

sudo mount /dev/sda2 /mnt

sudo cat /mnt/etc/fstab (to check the mount point of your ESP)

sudo mount /dev/sda1 /mnt/efi (or /mnt/boot/efi)

Now your installed system is mounted.

yeah it looks like the nvme drive only has one partion.

is the drive accessible through the live environment?

I was able to continue the steps ignoring mounting to ESP and I got back in :smiley:
