[Bug 2067622] [NEW] cryptsetup-initramfs disappeared during upgrade from 23.10 to 24.04 leading to failing boot

[Beda Kosata]

Public bug reported:

I have a system with a full-disk encryption installed with 23.10. After
doing an upgrade to 24.04 from command line using `do-release-upgrade`
(everything went without a problem), I rebooted and got a initramfs
prompt complaining about root filesystem not being available.

I was able to boot using the kernel from the previous version (6.5.0)
and after inspecting the system, I found that the `cryptsetup-initramfs`
package was not installed. After installing it, it produced a new and
slightly larger initramfs. With it, I was able to boot with the 6.8.0
kernel.


>From the upgrade logs, I can see the following:

```
Investigating (0) cryptsetup-initramfs:amd64 < 2:2.7.0-1ubuntu4 @ii gK Ib >
Broken cryptsetup-initramfs:amd64 Depends on cryptsetup:amd64 < 2:2.7.0-1ubuntu4 @ii pgP > (>= 2:2.7.0-1ubuntu4)
  Considering cryptsetup:amd64 10000 as a solution to cryptsetup-initramfs:amd64 0
  Removing cryptsetup-initramfs:amd64 rather than change cryptsetup:amd64
```

Which I think is the culprit of the problem.
