fails to start cryptswap

[Eric Phetteplace]

Background:
1. Fresh boot
2. Suspend, and computer appears to suspend.
3. Resume and computer resumes.
4. Try to shut down, and it will not.
4a. Message in /var/log/syslog: Failed to start poweroff.target: Transaction is destructive.

I am reporting this bug after a fresh boot, using ubuntu-bug

Perhaps this is the underlying issue. I have a relatively new install of Ubuntu 15.04. During install, I chose to encrypt my partitions. Upon booting, I enter my key for the primary partition and the swap partition. I don't think cryptswap is properly starting:

ericp@pucky:~$ systemctl list-jobs
JOB UNIT TYPE STATE
563 dev-mapper-cryptswap1.device start running
564 dev-mapper-cryptswap1.swap start waiting
549 <email address hidden> start running

Running top, I see swap is allocated, and I've seen it being used. I'm not sure what it never gets to a happy state.

Indeed this sounds like one of the recent cryptswap bugs: bug 1447282, bug 953875 (which are both fixed in -updates) and perhaps bug 1453738 (but this only applies to LVM which you don't seem to use). Please copy&paste the output of

  sudo blkid
  ls -lR /dev/disk/by-uuid
  grep -v '^#' /etc/fstab
  cat /etc/crypttab

Thanks!

Indeed! After a little more investigating, I commented out two lines in my fstab. I've been manually mounting the encrypted swap partition since then.

fstab - I'm including the lines I commented out:

There it is. Interestingly enough, I've been using /dev/mapper to manually mount dm-3 as my crypt swap, and it's been working fine.

Ah, so you do use LVM after all. So this is bug 1453738. So removing "cryptswap1" from /etc/crypttab and /etc/fstab is correct. You can/should leave sda5_crypt so that you retain some swap (that's the encrypted one).
