Some important points to add to my previous post: 1) This worked for me. However there is NO GUARANTEE that it will work for you, hence, point 2)
2) If you don't have a fresh installation, BACK UP YOUR DATA before any attempt at playing with your partitions. I have a couple of "scars" that show I'm damn right :-) 3) Be particularly careful when you edit /etc/crypttab . Change ONLY the cryptswap1 line. Leave the line starting sd[XY]_crypt alone Good luck! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/953875 Title: Encrypted swap no longer mounted at bootup Status in eCryptfs: Fix Released Status in systemd: Fix Released Status in ecryptfs-utils package in Ubuntu: Fix Released Status in systemd package in Ubuntu: Fix Released Status in ubiquity package in Ubuntu: Fix Released Status in ecryptfs-utils source package in Vivid: Fix Released Status in systemd source package in Vivid: Fix Released Status in ubiquity source package in Vivid: Fix Released Status in systemd package in Debian: Fix Released Bug description: SUMMARY ======= During installation with "encrypt my home folder" mode, a broken /etc/crypttab gets created which defines a non-existing swap device (usually "cryptswap1") with a UUID. This will also be put into /etc/fstab. As after installation the UUID does not exist, such systems don't have any actual swap. UPGRADE FIX =========== An upgrade to Ubuntu 15.04 ("vivid") will detect and comment out these broken swap devices from /etc/fstab and /etc/crypttab. If you actually want to use those, do these steps: - Find the swap device that was meant to be used in "sudo fdisk -l" (it should say "Linux swap" in the last column), remember the device name (something like "/dev/sda5") - Find the UUID in /etc/crypttab (the long alphanumeric ID after UUID=) - Run "sudo mkswap -U 1234... /dev/sda5", replacing "1234" with the above UUID, and /dev/sda5 with the device name from step 1. - Edit /etc/crypttab to append ",offset=1024" in the fourth (last) column of the cryptswap1 line; ensure that there is *no space* between the "cipher=aes-cbc-essiv:sha256" and the appended option. If there is a leading "#" in the file, remove that too. - If there is a leading "#" in /etc/fstab in the line starting with /dev/mapper/cryptswap1 line, remove that. - Run "sudo update-initramfs -u". ORIGINAL REPORT =============== Clean install of 12.04 and with encrypted home for my user. Did all updates and now the bootup hangs waiting for swap to become available and it never seems to ever finish.
