I’ve updated my system today and upon reboot I could start my luks encrypted system anymore.
When I entered my password I was welcomed with:
Failed to start Cryptography Setup for luks-xyz
See 'systemctl status "systemd-cryptsetup@luks-xyz..service"' for details.
[DEPEND] Dependency failed for Local Encrypted Volumes.
[...]
Warning /dev/mapper/luks-xyz doesn't exist.
Scary thing to read. Seems like my main partition doesn’t exist anymore.
Hopefully my main partition still exists. The issue was with my password: I’ve configured and always used this system with an azerty keyboard configuration; the update changed the layout to a default dumb-hat qwerty.
That really sucks.
Where do I report that? I don’t know if it’s a kernel issue, a cryptsetup issue, an arch or endeavour one.
Yeah, that error just indicates your device failed to unlock, not that the partition is missing. /dev/mapper/* is a device that is created to access the unlocked partition. Since it failed to unlock, it doesn’t exist.
You are the second person to report this today. It may be a dracut issue. I will open an issue upstream.
EDIT: It has already been reported and a fix is in progress:
