Kernel Panic due to Shared Library

Did a quick pacman -Syu, everything updated without a hitch, looked completely fine, reboot to a kernel panic.
The exact error is this:

I have tried booting into installation media however using any command using pacman in a chroot results in:

/bin/pacman: error while loading shared libraries: liblzma.so.5: cannot open shared object file: No such file or directory

EDIT: This is a file owned by xz

Re: Kernel Panic due to Shared Library

the output is self evident, what do you get when you

ls -l /usr/lib/liblzma*

Re: Kernel Panic due to Shared Library

Does the error message not clearly tell you that liblzma.so.5 is missing?

[eschwartz@arch ~]$ pacman -Qo /usr/lib/liblzma.so.5
/usr/lib/liblzma.so.5 is owned by xz 5.2.2-2

Something terrible happened to your "xz" package, clearly, which broke systemd (rather major, that).

Given that you have a broken system, why on earth would chrooting back into the broken system help? Certainly not when pacman uses libarchive which also links to the same missing library.

...

From your installation media, use pacman with --root, or alternatively let pacstrap do the work for you just like it did when you first installed.
You will need to reinstall xz at a minimum, but if that was broken, who knows what else might be...

Re: Kernel Panic due to Shared Library

It looks to me like it's your initramfs that's broken. Chroot into the installation and regenerate it.

Re: Kernel Panic due to Shared Library

In installation media: run pacstrap /mnt xz.

error: xz: signature from "Pierre Shmitz <pierre@archlinux.de>" is invalid
:: File /mnt/var/cache/pacman/pkg/xz-5.2.2-2-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
error: failed to commit transaction (invalid or corrupted package (PGP signature))
Errors occurred, no packages were upgraded.
==> ERROR: Failed to install packages to new root

Note: It did not give me the opportunity to delete the package. It continued immediately
Tried updating with pacman but it also fails because files exist on the filesystem.
Can't remove the package because it breaks dependencies

EDIT: Force reinstalled xz using pacman -root /mnt -S --force xz
This worked however I am receiving another kernel panic upon reboot for libgpg-error.so.0
Will repeat the process above and try again...

EDIT 2: This would have been resolved had I followed this in the first place.
However, unfortunately I broke my system to the point where it is easier to reinstall than fix it.

So why does pacman in a chroot fail as well, as per the first post?

Re: Kernel Panic due to Shared Library

I missed that. So both were broken.
