[SOLVED] Failure to boot after update: Waiting 10 seconds for device

Hello,

Running `pacman -Syu` caused a problem similar to https://bbs.archlinux.org/viewtopic.php?id=217104 , then I booted from a flash-drive, chrooted into it and ran `pacman -S linux`. Then I tried to boot:

...
:: running hook [encrypt]
Waiting 10 seconds for device /dev/disk/by-uuid/65280982-f6db-45b8-906e-a376855b34dc ...
Waiting 10 seconds for device /dev/MyVolGroup/root ...
ERROR: device `/dev/MyVolGroup/root` not found. Skipping fsck.
:: mounting `/dev/MyVolGroup/root` on real root
mount /new_root: no filesystem type specified.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off
[rootfs ]#

As a side note, the keyboard did not work in this emergency shell.

Any Ideas?

Me reinstalling stuff and more info: https://pastebin.com/DXjkhZTL

My /etc/fstab

# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>
# /dev/mapper/MyVolGroup-root

UUID=d5f62749-bdb5-4e9c-9b75-44e79c1ffa4e    none          swap          defaults      0 0

UPDATE:

The problem was (probably) that I rebooted before `pacman -Syu` finished. Booting from a stick, chrooting into it and running `pacman -Syu` fixed it.

Would you happen to have the journalctl of the fail mount ?

There is no log:

`journalctl -b -0` gives me the log of chrooting into it and `journalctl -b -1` gives me the log of the last successful boot.

This is expected, because it fails before prompting for decryption passphrase.
