Error on shutdown: Failed deactivating swap /dev/disk/by-id/dm-name-cryptswap1.

[Laurent Bonnaud]

Hi,

I am using encrypted swap on this system for years, it works well, but I recently noticed the following error messages on shutdown:

Mar 16 08:22:31 xeelee systemd[1]: Failed deactivating swap /dev/disk/by-id/dm-name-cryptswap1.

On another system upgraded to zesty I get different error messages:

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[dino99 (9d9)]

For the record, this is also ramdomly happening with swap partition not encrypted.
Kind of race i suppose, but cant determine what exactly.
So cryptsetup seems not the main reason of that problem.
Note that cryptsetup is installed due to some packages's dependency.

[Steve Langasek (vorlon)]

Dino99, this bug report clearly references a device which has "cryptswap" in its name. Saying that it happens on systems without crypted swap enabled, without defining what "it" is, is not helpful. Please file a separate bug report for your issue.
