After changing the resume policy to 'none' and updating initramfs, the
system will boot, but with a long delay. There are also now very long
delays to ssh logins.
I've attached the syslog from the boot.

Long time booting : Failed to connect to lvmetad. Falling back to
device scanning.

Bug description:
[SRU Justification]
A regression in initramfs-tools causes it to autogenerate config in the
initramfs saying to resume from any available swap devices, but references the
swap device by UUID, which is not a canonical form for referring to LVM volumes
(because of snapshotting, they are not unique). Ubiquity also generates a file
in /etc at install time which references the swap partition in the same way.
Since the lvm2 initramfs hooks also only activate precisely those LVs that are
detected as needed at boot, this adds an inappropriate 30-second boot delay to
any system with swap on LVM, which includes any desktop system that was
configured with LVM (but not full-disk encryption) at install time.
[Test case]
1. Install using the "Use LVM" option in the desktop installer.
4. Reboot.
5. Verify that dmesg shows a 30-second delay before mounting the root
filesystem.
6. Install initramfs-tools from bionic-proposed.
7. Reboot.
8. Verify that dmesg no longer shows a 30-second delay before mounting the
root filesystem.
9. Install using the bionic daily image that contains the ubiquity from
bionic-proposed.
10. Reboot.
11. Verify that /etc/initramfs-tools/conf.d/resume is not present and that
there is no delay before mounting the root filesystem.
[Regression potential]
This makes changes to shell scripts, and shell is a perilous language. An
unnoticed bug could cause all initramfs generation, and thus all kernel
installation, to fail for some users. A regression could also cause a user to
lose hiberation support that they currently have.
[Original description]
After choosing "Erase disk and install ubuntu" + "Use LVM with the new Ubuntu
installation", the
system is very slow to reboot.
It shows the message : "WARNING:Failed to connect to lvmetad. Falling back to
device scanning.",
then waits 32 seconds, then continues as it should.
I think this is a ubiquity bug, since the d-i based installer is not affected.
