[Bug 484429] [NEW] Plugging in a LUKS device causes the following error: Error unlocking device: cryptsetup exited with exit code 239: Command failed: Device already exists

[komputes]

Public bug reported:

Binary package hint: cryptsetup

Steps to reproduce:
1) Go into palimsest (disk utility) and create an encrypted partition on an external disk.
2) Quit Palimsest
3) Pull the USB stick
4) Intert the USB stick

Result:
GNOME displays a dialog for the password. Once submitted, the following error comes up:
Error unlocking device: cryptsetup exited with exit code 239: Command failed: Device already exists

This is due to the mapping being Opened when the disk is created, but
never closed, which creates a conflict.

Workaround:
Do the following to resolve the conflict of the existing device i /dev/mapper.
$ ls -al /dev/mapper
(Identify the mount point for your drive, "sudo blkid" may help)
$ sudo cryptsetup luksClose devkit-disks-luks-uuid-<uuid>-uid1000

What is expected:
Palimsest (Disk Utility) is expected to  "cryptsetup luksClose" the mapped device when finished creating the encrypted partition.
