[SOLVED] where should I mount chroot?

My system was up and running since long time without any issues until last update from yesterday. Since then I can't boot anymore (Light Display Manager failed). I'm trying to downgrade the packages mentioned on this post.

I'm running a USB stick with Arch and I'm trying to chroot into my system but I can't do it.

root@archiso ~ # arch-chroot /mnt /bin/bash
mount: /mnt/proc: mount point does not exist.
==> ERROR: failed to setup chroot /mnt

I'm not sure how to proceed. Obviously I think I should create a /mnt directory but I would like to be sure about it and don't mess up my system.

Thanks in advance.

Re: [SOLVED] where should I mount chroot?

If only your graphical login is failing, switching to a different tty should be enough (i.e. no need to use an Arch USB).

The usage of the arch-chroot command is slightly different: Mount all your filesystems {/dev/sdX} to /mnt (the emphasis lies on "all", for example forgetting to mount the boot partition in this step is a common source of errors), i.e., such that "/" of your main drive is located at /mnt of the usb. Then run "arch-chroot /mnt".

This was covered in the installation guide, did you follow it?

Thanks for your reply. I already try to switch to a different tty without success (try CTRL+ALT+F1 up to F12). With some of them, the error dissapears but it doesn't enter into a console.

I read the installation guide but I wanted to be sure that I don't mess up anything.

Fair enough.
Remember to mark your issue as solved if "arch-chroot" worked; if not, feel free to report back with any errors you have encountered.
