Bug ID: 474481
Summary: Freshly installed Neon on a LUKS encrypted disk fails
to boot due to missing passphrase prompt

SUMMARY
Due to a failed disk I have to reinstall Neon on my notebook (ie. I know it
worked before even though it was a while since I last installed). I'd normally
use LUKS+LVM but that is broken (cf. bug 432305) so I amended my partitioning
slightly to install the system first on a smaller LUKS encrypted partition and
rsync it over to LVM later on. This resulted in a slightly weird partition
scheme as shown under ADDITIONAL INFORMATION.
Installation succeded and I rebooted. After the reboot I was not asked for my
LUKS passphrase though but was presented with a repeated error message
"cryptsetup: ERROR: luks-$uuid: maximum number of tries exceeded". Hitting
escape shows a "No key available with this passphrase" even though I am never
asked for one. After a while I got dropped to the initramfs shell.
I can reproduce this; on a second try I even wiped all the partitions to make
sure no leftover data confuses the system.
STEPS TO REPRODUCE
1. Boot into Neon User Live ISO (neon-user-20230907-0716.iso)
2. Start installer, go to Partitions
3. Select Manual Partitioning
4. Create a partition table similar as the one listed below:
* nvme0n1p1 /boot/efi fat32
* nvme0n1p2 /boot ext4
* nvme0n1p4 / btrfs on LUKS
5. Finish installation
6. Reboot
OBSERVED RESULT
I am not asked for my passphrase and thus can't boot
EXPECTED RESULT
The passphrase prompt should appear
