I don't get this at all. Is there any way to give more detail instruction as to how to get into encryption, or am I totally screwed!
You will get it, you need to cool down. Everything will work! You'll get your computers back! :) Do you remember, you managed to set up encryption yourself without much help.
Instructions:
1. You need to boot with a live CD
2. you need to install the package downgrade
3. you need to unlock your encrypted root partition https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption#Unlocking.2FMapping_LUKS_partitions_with_the_device_mapper
3. you need to mount your root partition https://wiki.archlinux.org/index.php/change_root#Partition.28s.29_mount
4. you need to chroot into your root partition https://wiki.archlinux.org/index.php/change_root#Using_chroot
5. you run downgrade linux41
6. you run update-grub
7. you run cryptsetup close root (as described in the lin in 3.)
8. you reboot without live CD

@eugen-b,

Thanks for getting back to me, as I'm in the state of panic now! Not only this update screwed several of my computers, but it also destroyed my wife's computer. So I'm really in a big trouble now! I installed encryption through the installer, and not manually. I'm not a technical guy, and primarily a GUI user, and that's why I'd chosen Manjaro, because your don't have to be a computer guru to use it.

In any case,  I have the Manjaro KDE 15.12 on a stick, that I can boot into it, but I don't see how to install the package downgrade. So how can I install the downgrade package?

Manjaro is a dangerous beast, it seems easy to run, but can easily break due to its rolling nature. You always need to have a strategy for the case that it breaks.

I thought I did, and that's why I installed several other kernels, but non have worked! And that's why I went with the STABLE version! So am I screwed here?

I encrypted the HDD on my laptop when I installed Manjaro a year ago. Luckily for me, I recently updated the kernel to 4.5, so the upgrade didn't affect my setup. In short, I've had no issues. Thanks again Phil and Co.  :)
OK, so I took the red pill. Now what?

I've updated the fix-tutorial to the latest information. Sorry that I had no time to dig deeper into it earlier. User updating now should have no issues anymore with it.

@philm,

So is there anything I can do to at this point?

Manjaro is a dangerous beast, it seems easy to run, but can easily break due to its rolling nature. You always need to have a strategy for the case that it breaks.

This should not be the case - the 'stable' branch should not break!

However - what this illustrates (once again) is that more people need to run on the testing branch and actually TEST things. The Manjaro team is small and (even if it wasn't) they can't hope to test every package against every configuration.

If you are running a slightly offbeat configuration, or have multiple PCs, it's in your interest to run at least one on the testing or unstable branches to spot these issues early.

Edit: I should say that I do agree on having a recovery strategy for any encrypted device. If something does break (whether your own fault or a bug) you're SOL otherwise.

Yeah, and it‘s so easy to have another partition with a testing Manjaro system on it. You would update it before your productive system. You don‘t need to have a second machine for that.

Update on the encryption thingy. Well, if you have encrypted your system with cryptsetup 1.7.0-1 or earlier, you will still have a problem, as in the kernel doesn't support the old API anymore. So the only option for you is to keep the old kernel, until upstream has fixed that. Simply don't encrypt your HDDs :P
Are you serious? I don't like the sticking tongue here. You don't want us to encrypt our devices? Are you working for the government?

Thanks for the manual for repairing though, but i exepected better form Manjaro.

@Thijs, let's discuss here: Why root encryption?

Ok, I boot the live cd, and opened a terminal.
I typed "sudo cryptsetup luksRemoveKey /dev/sda2"
No success.
The instruction says: # cryptsetup open --type luks /dev/<partition name> <device-mapper name>
I'm lost from here. When I try to delete the encryption key by typing this command "sudo cryptsetup luksRemoveKey /dev/sda2", it says no key found.
Sadly, I am totally lost.
