This report it to narrow down what is apparently a pretty common bug.

I've done eight installs to cover the four normal variations with and without encrypting the home folder.

Every time the home folder is encrypted the new install has a broken swap. Each of the installs with a broken swap has a boot that 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
