[Resolved] Unable to chroot with install media

ThePrivacyPlayer · 2025-05-03 21:37:07

Hi everyone,

I finally got started on arch a couple of days ago. I got a working install with hyprland (yes, I'm going all in), and it appears my sudo is somehow broken (I believe I had to install it myself with pacman, as it wasn't installed by default), and was getting the error "/usr/bin/sudo must be owned by uid 0 and have the setuid bit set version".

Finding the discussion in https://stackoverflow.com/questions/370 … ion-ubantu, I went back to my install media (on external usb) to fix it as shown.

However, when trying to arch-chroot after mounting my ESP and root partition, it tells me that /bin/bash does not exist. Since this is a symlink for /usr/bin/bash, I tried adding it as an argument, and receive the same error "/mnt/usr/bin/bash: no such file or directory".

After checking a bit in the file structure, it appears that when mounting my partition, the whole partition is somehow actually mounted to /mnt/@ instead of /mnt, and therefore I'm unable to chroot to it.

Any idea if I messed something up here? I didn't find any reference to this happening to anyone else.

Thanks in advance for your help!

Did you install the base package in your chroot root ? https://archlinux.org/packages/core/any/base/ It's needed to create bash process in your chroot environment.

You can do it like this:

pacstrap -K /mnt base

If that's not the case then please send the command output of lsblk with your partitions mounted.

I'm not sure I understand what you mean. I already have a full system installed, which I can launch and log into just fine.

However when using the arch installer, there seems to be some kind of issue of how the partition is mounted.

Also, I need to chroot into my actual system. As I understand it, if I install the base package, it will create a new install separate from my existing one and that's what I'll chroot into. Am I understanding this correctly?

Hereunder you can see my lsblk as well as the files in /mnt and /mnt/@

As you can see, my whole system is mounted under /mnt/@, which I cannot chroot into.

You're already root, why are you trying to use sudo?

And you need to chroot into the root filesystem, you don't have the correct subvol mounted to /mnt.

I'm totally confused by your reply. My screenshot is from the arch installer, that's why I'm root. I never login as root on my actual system.

As for the subvol, that's exactly my issue. I installed everything on my nvme0n1p2 partition, which I mounted to /mnt during install. And as you can see from lsblk, I mounted the partition to /mnt again here, and my question is why the file system is in /mnt/@ instead of /mnt? When I try to to chroot to /mnt/@, it tells me it's a non-directory, so why is my system mounted there when I used mount /dev/nvme0n1p2 /mnt, just like every single other time I did it, including during install?

you selected BtrFS for your system partition - so you must mount it with the required BtrFS subvol parameter: https://wiki.archlinux.org/title/Btrfs# … subvolumes

Thanks a lot, worked like a charm!
