> From your description it sounds like something is destroying sda3 itself (i. e. the outer encrypted LUKS partition), *not* the unencrypted sda3_crypt, right?
Right. I've created the partitions with the graphical xubuntu installer from xubuntu 15.10 beta 1 cdrom put on a usb stick, and created both sda2 and sda3 as encrypted volumes, then put a swap in sda2_encrypted and btrfs in sda3_encrypted. This worked well with 14.04. After booting I've realized that the machine had no swap, even no links to the partition under /dev/disks/by-uuid, and thus could not open the device manually. I found that the partition was completely filled with random data, no luks header. cryptsetup isLuks said it is not a luks device, and xxd should no trace of a luks header anymore, completely overwritten. I assumed it was a problem of the installer, not of the running system. My first suspicion was a corrupted partition table, but I did not find any problem with the partition itself. My next suspicion was a fault in the storage device, since I had replaced the old hard disk with a brand new SSD for the fresh install, but except from that problem I do not see any problems with storage, and I experienced these problems on two distinct machines. I do not see any problems on the other partitions and their file systems so far. > - What do you precisely do to "repair the swap manually"? cryptsetup luksFormat -c aes-xts-plain64 -s 512 /dev/sda2 (and enter the same password as for the root partition sda3) cryptsetup luksOpen /dev/sda2 xxx mkswap /dev/mapper/xxx On one of the two machines (office machine, I'm using right now) this helped and the problem did not reoccur so far. That's why I first assumed that it was just a problem of the installation process (graphical xubuntu installer), because I had experienced more trouble with the installer used in the lubuntu 15.10 beta cdrom image. I did the very same thing at my machine at home, also ran into that problem, again assumed that it was a problem of the xubuntu installer, fixed it as described above, but it reoccured. (Meanwhile there's more trouble with this machine, systemd hangs in the boot process, except when I open an emergency root session.) >- After that, please copy&paste the output of ... I'll reply to that once I am back home at that particular machine. -- 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/1506139 Title: 15.10beta crashes encrypted swap partition Status in systemd package in Ubuntu: Incomplete Bug description: Hi, I'm usually using a setup with three partitions on a disk Partition 1: plain ext4 boot partition mounted on /boot Partition 2: luks-encrypted swap Partition 3: luks-encrypted btrfs for / /home ... both mentioned in /etc/crypttab like sda2_crypt UUID=a7976d5c-6191-436d-9cf9-2cedf17d0893 none luks,swap,discard sda3_crypt UUID=339b9a90-8292-422d-a3cf-eeb0317e9f84 none luks,discard With several machines I have installed 15.10 beta on and in several cases I experienced the problem that the swap is not activated at boot time and that /dev/disks/by-uuid does not contain a link to the swap partition, and the previously created luks-encrypted swap is destroyed after boot: It is not a luks partition anymore and filled with random (presumably encrypted) bytes without structure. I first thought that this is a problem of the setup process, and repaired the swap manually. But then I found the partition destroyed again. This happend several times on several machines. I am not sure yet what exactly would destroy the partition.
