I posted this in the Absolute beginners section awhile ago, but received no replies...so I'm trying again.
Complete Ubuntu beginner here. Just installed ubuntu and have had this issue from the beginning.
Upon startup, I get flashed the message: The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present. Continue to wait, or Press S to skip mounting or M for manual recovery.
This quickly goes away and boots normally as far as I can tell.
I don't know whether anything detrimental is actually happening, but I'm still worried.
After a fair bit of research I've found that most people suggest commenting out the "/dev/mapper/cryptswap1 none swap sw 0 0" line in /etc/fstab, however some people have stated that this merely masks the issue and doesn't actually fix the problem;
[For all the newbs like me out there, /etc/fstab is a FILE that can be opened in a text editor. /etc/fstab.d is a FOLDER (which for me is empty) and is not what you're looking for.]
This link is one of the ones that suggests commenting out the above line: http://askubuntu.com/questions/56843...per-cryptswap1
However, it also propose a few checks. Here are the results when I run those checks:
Contents of /etc/fstab:
# /etc/fstab: static file system information.

ls: cannot access /dev/disk/by-uuid/218fc5d5-0014-49a7-8fbb-8bcd97300f36: No such file or directory
If I just use "ls -l /dev/disk/by-uuid" I get:

It doesn't seem to finding the swap partition at all (if I'm interpreting this correctly), but as far as I can tell from other checks it is there.
e.g. "sudo fdisk -l /dev/sda" returns
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 296876031 148436992 83 Linux
/dev/sda2 296878078 312580095 7851009 5 Extended
/dev/sda5 296878080 312580095 7851008 82 Linux swap / Solaris
and "swapon -s" returns
Filename Type Size Used Priority
/dev/mapper/cryptswap1 partition 7851004 0 -1
Basically I have no clue how to proceed.
