How to update grub in a encrypted partition

Yesterday I made an update in my Ubuntu 16.04. During the update, a grub screen appeared. A black screen with only this message :
GNU GRUB version 2.02~beta2-36ubuntu3.16
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.
grub >
I touch the TAB touch, it shows me a lot of commands, but I don't know which one would be useful.
I try to restart my computer, but I fall into this screen immediately, without loading Ubuntu.
I have make a Boot Repair report, you can see it in this link :
boot-repair report
I find some people which have the same problem. They say it's a grub problem, which can be corrupted during its update.
But I cannot simply update grub : the specific part of mine is that I use encryption of my disk. This is why Boot-repair cannot provide me a solution.
I ran a live-usb key with Ubuntu 14.04, I see my partition with my data, but I cannot access to it because of permissions (I don't have any right, so I cannot make backups).
I hope someone will help me to repair grub with this encryption.
Cheers

I have posted below before, but was delete, because question asked was similar problem with grub, but without encryption. This is how I solved my grub problem with LUKS encryption:
After updating (by ubuntu software) my laptop today (after not using it for one week) I have the same problem. Only a grub prompt. Also first tried Boot-Repair on Live USB, but didn't work. My laptop is luks encrypted, so searched for other solutions, I found:
grub> ls
(hd0) (hd0,gpt3) (hd3, gpt2) (hd0,gpt1)
grub> insmod luks
grub> cryptomount hd0,3
Enter password
Slot 0 opened
grub> insmod lvm
grub> ls
(crypto0), etc.
grub> configfile $prefix/grub.cfg
This gives normal luks password entry screen, which accepted, but after that it immediatelly gives the following warning:
Welcome to emergency mode! Etc. I have looked at the journal and found (in red):
fsck failed with error code 4 and
Failed to start File System on /dev/disk/by-uuid/etc-etc.
Next thing I did was, enter maintance mode and command:
fsck /dev/sda2
After that I was able to log in normally, update by terminal and reboot. Did get another failure and had to run fsck /dev/sda2 again. After that I was able to reboot normally.
So this solved the above problem (when you have an encrypted LUKS disk).
