Swap partition with encrypted system - Ubuntu 18.04
0
I have installed Ubuntu 18.04 with this method.
In the partitionating step I have created space for the swap.
The problem is that the system fails to hibernate. I suppose for problems related to the encryption.
Here it is my situation:
Device Start End Sectors Size Type
/dev/sda1 2048 534527 532480 260M EFI System
/dev/sda2 534528 567295 32768 16M Microsoft reserved
/dev/sda3 567296 191895551 191328256 91,2G Microsoft basic data

/dev/sda6 193943552 468375551 274432000 130,9G Linux filesystem
/dev/sda7 468375552 499095551 30720000 14,7G Linux swap
Partition table entries are not in disk order.
Disk /dev/mapper/cryptroot: 130,9 GiB, 140507086848 bytes, 274427904 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/vgroot-lvroot: 130,9 GiB, 140504989696 bytes, 274423808 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
In particular, /dev/sda6 is for the system and /dev/sda7 is for the swap.
The fstab file:
sivlab@sivlab:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#

18.04 should work with a swap file rather than swap partition. Encryption should not be a problem, however what works for me as far as encrypted swap partition goes: help.ubuntu.com/community/ManualFullSystemEncryption/…
