Okay, I've now done the same eight installs on a different box, and using the 64bit Mate instead of 32bit. I got the same result:

Every time the home folder is encrypted the new install has a broken swap. Each of those boots includes the common error 'keys:Continue to wait, or press S to skip mounting, or M for manual recovery'.


1. LVM with encrypted home
- error on boot
2. LVM without encryption
- no error
3. LVM with LUKS with encrypted home
- error on boot
4. LVM with LUKS only
- no error
5. Standard install with encrypted home
- error on boot
6. Standard install without encryption
- no error
7. 'Something Else' with encrypted home
- error on boot
8. 'Something Else' without encryption
- no error
