<div class="moz-cite-prefix">I tried Puny Geek's method (ref:
below), creating the missing resume file after mkswap. While the
process seemed go to a successful completion, /swap was gone after
reboot. Not to mention, the partition with /swap on it could no
longer be "activated." I had to delete and recreate the /swap
partition. At this point, as discussed previously, I'm ready to
opt-out of an encrypted /swap but how do I get rid of the traces
of encrypted swap and the associated error message at boot?<br>

When I boot, I see, "The device mapper
for /dev/mapper/cryptswap1 is not ready
or not present. Continue to wait, or
Press S to skip mounting or M for manual
recovery.<br>
<br>
Waiting has no apparent effect; M does
nothing.<br>
<br>
Gnome-system-monitor shows swap as not
available. Gnome-disk utility shows the
partition as inactive and when I
Activate it, the swap status changes
immediately to available.<br>
<br>
After a reboot, I get the same message
at boot, swap is not available and is
not active, according to Gnome-disk.<br>
<br>
I'm running Xubuntu 14.04 and updates
are current. But, I've seen the same
message at boot on another PC running
Xubuntu 12.04.<br>
<br>
Luckily, Linux manages memory memory
quite well so swap is seldom called into
action, and, I don't hibernate - just
suspend or shutdown.<br>
<br>
Solution? <br>

Marcos: did not work. I tried it last night. I did a little more
research and found this is very likely related to a bug, <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1153661">https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1153661</a><br>
<br>
In short, it appears to have been around since ver. 12.04 with
various attempts to cope with little success.<br>
<br>
In the short-term, it appears to me that the best solution is to
dump encryption of /swap and go with a non-encrypted swap. BUT, I
don't know how to do that!<br>
<br>
More comments:<br>
<br>
The encryption of /swap appears to be a byproduct of opting to
encrypt /home during install of Xubuntu. This happened without my
explicit invoking this option during install on two different
systems.<br>
<br>
As noted by others, the UUID for encrypted swap is not correctly
identified in /etc/crypttab as well as in /etc/fstab.<br>
<br>
Some suggest that the error is related to having installed from a
thumb drive, which is what I did.<br>
<br>
Puny Geek suggests updating /etc/initramfs-tools/conf.d/resume.
That file does NOT exist on my 14.04 install.<br>
<br>
As others have noticed, some fixes work for a current session but
don't survive a re-boot. I had this experience by "activating" the
/swap partition with the Disk Utility, previously known as
"palimpsest" under 12.04.<br>
<br>
I concluded that, since this bug has been long-standing and others
have not been successful in fixing it or having a lasting
work-around, I'm not likely to be successful either. Hence the
conclusion of living without it being encrypted is a nice work
around. I encrypt /home on my portable devices to protect personal
info if it is stolen. My guess is that it's unlikely for
unencrypted info to be compromised because it's unlikely to sit in
/swap and be read by a nefarious operator.<br>
<br>
Thanks to all who thought about this.<br>

Oh: here's one I did not try: treating this as a timing error

<br>
Other thoughts:<br>
Try creating /etc/initramfs-tools/conf.d/resume with the correct
UUID and go through Puny Geek's approach.<br>
Hope for a solution in response to bug report.<br>
<br>
p.s. All of this fiddling around is what I anticipated when
attempting a solution and why I put it off!<br>
