Hi again, John Hupp helped me find more information about the cryptswap bug. See comment #37 of the bug report https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/953875 I can confirm that it works as a work-around, and there should be enough information in the bug report https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1310058/ to squash that bug. We are also getting help from ventrical at the Ubuntu Forums to test various encrypted systems. See the following link http://ubuntuforums.org/showthread.php?t=2266912 I try to sum it up in post #35 of the Ubuntu Forums thread. -o- We should not be surprised that 'Encrypted home' is no longer part of any [other] Ubuntu flavour test-case. It does not work :-( There are certainly user cases, where it would be useful, but 'Encrypted home' has been buggy since March 2012 when Alan Pope reported bug #953875. I think it is a bad idea to make a separate test-case for it now. So let us go ahead with the alternate test-cases, modified only at these places: ----- 'No' for encrypted home directory # Changed from 'Yes'. This is the most important modification. 'Yes' unmount mounted partitions in the target drive # Additional item which is important. 'No' to install grub boot loader to master boot record. Instead select the target drive for the bootloader manually. # Changed from 'Yes'. This is optional but I recommend it because the automatic choice often creates problems for me. ----- Best regards Nio -- Mailing list: https://launchpad.net/~lubuntu-qa Post to : lubuntu-qa@lists.launchpad.net Unsubscribe : https://launchpad.net/~lubuntu-qa More help : https://help.launchpad.net/ListHelp
