Yesterday I did a new installation on my laptop. With luks encrypted btrfs and a swap partition for hibernation. The installer gave me these options.
But now, when I start the laptop it says:
Failed to open key file.
ERROR: resume: hibernation device '/dev/mapper/luks.....'
Nevertheless the laptop starts and I can log in. And the free command shows that swap is on.
Any idea what is going on here? I certainly need hibernation.
No resolution found yet …
Hello, I installed EndeavourOS on my DELL XPS 15 laptop, no dual boot, default BTRFS partition layout with swap & hibernate, and encrypted partition.
At boot, after entering the correct partition encryption password, and choosing one of the boot options in GRUB, I see:
Starting version 249.4-1-arch
Failed to open key file.
And then a completely black screen… I don’t know if it’s related, but this happened after I ran nvidia-installer-dkms, without errors. Also, secure boot is disabled.
This …
What are the contents of /etc/crypttab ?
Can you decrypt from live environment using the keyfile?
sudo cryptsetup open /dev/sdxY --key-file=[path]crypto_keyfile.bin crypt
Personally I think this is an existing issue with the new installer and btrfs on luks with swap.

swap is working just fine. The system is swapping. I checked it with the stress tool. That tells me that the key file is working. key file in crypttab is /crypto_keyfile.bin. Same file as for /.

Curious. I dumped my Arch and moved to EndeavourOS to one machine and had same error on fresh install too. Same as @Moultipass fresh install.
“Failed to open key file” at boot, after GRUB
Although I can easily re-install and run my package scripts & configs to be back up and running in 15 mins…still would be curious on this

@mbod I found a github issue that has a suggested fix and at first glance looks like it resolved this issue on my manjaro system, needs more testing though.

I was considering a swap file on btrfs. But the documentation says it needs to be located on an uncompressed volume. Didnt want to look up how to do that. And resume_offset calculation is more complicate too. I didnt want to go that way. Too complicated. I am back to XFS + swapfile.
