  • What is this about? I need to setup some key? Or ignore it? This is new 17.10 installation. Swap is on, file /swapfile exists. Home encryption enabled, at setup.
  • How about SSD installation, may be swap should be turned off? RAM is enougn. Anyway I don't want to crypt it, processor is too slow.

leonid@LeonidMew:~/Downloads$ sudo update-initramfs -u

update-initramfs: Generating /boot/initrd.img-4.13.0-32-generic
cryptsetup: WARNING: Invalid source device /swapfile
cryptsetup: WARNING: target cryptswap1 has a random key, skipped

Update: What means priority -1, is it turned off?

leonid@LeonidMew:~/Downloads$ swapon -s
Filename                Type        Size    Used    Priority

It's a result of this bug:

https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1720036

It seems to just be an slightly irritating error message with no practical consequences and is safe to ignore

After this warning the next boot fails. While booting, the system is waiting for the encrypted swap file, but unsuccessfully. After a while a command prompt appears. For the normal boot the "exit" command have to be issued.

Solution:

sudo swapoff -a
sudo update-initramfs -c -k all
sudo swapon -a
