Messed up fstab - can't boot

seems I messed this up. Is there a way to access the fstab from outside and undo the changes?

It’s a while since I looked at the installer but I think you could do this:

  • make an install SD/USB
  • delete filesystem.tar.xz
  • add with
touch /mnt/root/etc/fstab
mv kernel.img kernel.nouse

Boot from the SD/USB. I haven’t tested this but worth a try.

You might be able to boot to the recovery console, mount the filesystem RW and edit it

:thinking: how would I do this?

I put the installer img in the USB port but this would format everything.

Is it possible to run any live usb system and then access the filesystem? I could not get into recovery mode, tried pressing Shift and Ctrl during startup

And: I don’t have a USB keyboard

How did you try that without a USB keyboard?

You’ll need a USB keyboard to make the changes.
But fstab shouldn’t actually be needed for the system to boot. The root= parameter is passed during boot.

tried it w/ a wireless keyboard…

Maybe I’m running into this issue not only for the fstab changes but also for the HDMI thing upon boot.

If you broke fstab then I’d expect a systemd unit to faiil on boot and the system to boot in a degraded state; but it should at least be booting.

asked the neighbor for a USB keyboard, still can’t boot

You might need to reinstall the system then.

Oh yes, it does that first. :roll_eyes:

okay, so I did a clean install and now I’m running into this problem again, see this thread

Have you tried a new PSU?

No, might be a stupid q, where can i get one. Which specs do I need?

Does it go through to the EU w/out customs? Otherwise postage and customs are more then the PSU, no?

ordered it anyway

We no longer send items DDP at this time of writing. So customs will indeed be involved.

This may change in the near future.

@sam_nazarko I received the new PSU but I’m still facing the same issue :frowning: - anything else I can do?
Update: I switched the HDMI cable, seems to work now. Very odd.

Glad to hear this. Could have been a short on the cable.
