[Bug 1917424] [NEW] LVM2 hook not executable; causes update-initramfs to miss adding lvm2 binaries

[Paul Goins]

Public bug reported:

I did an upgrade from Groovy to Hirsute today, but the upgrade did not
go well.

I run an encrypted LVM for my root Ubuntu partition.  My grub did not
get updated properly at upgrade time, but via a USB startup disk for
Hirsute I was able to repair this myself.  However, I spent hours trying
to get grub to detect my LVs.

Ultimately, I found the problem: /usr/share/initramfs-tools/hooks/lvm2
in the lvm2_2.03.11-2ubuntu2_amd64.deb package lacks an executable flag.
Running update-initramfs verbosely highlighted that the hook was not
getting fired for this reason.

Upon adding the executable flag to the file, I was able to use a chroot
to re-build the initramfs and get my system to boot.
